I've seen a few threads in this forum regarding XBR400 sets simply turning themselves off. I can hear my set powering on, the standby light blinks 10 times, then nothing. The light turns off. If I manually switch the set to standby the the lught stays solid red. I never see any picture.
I don't get a "morse code" blinking sequence or anything of that sort. I've already tried the basic troubleshooting steps without luck. I called Sony and they were most unhelpful.
People mentioned faulty d-boards being the root of this issue. Since my set is > 1 year old the only thing covered is the picture tube. How much does one of these boards cost and what can I expect as a labor rate for replacement? I'm scheduling a visit by a technician from the local sony authorized repair center ASAP. I'd like to be able to provide the technician with as much information as possible.
From what I've gathered here:
- I should insist on a NEW d board, not refurb
- The tube may have to be replaced
- It's going to take a long time
Anyone have any suggestions? Anyone who's experienced this problem have sage advice? Help!?!

Well, a month later and this saga is over. I was hoping to get some input from the forum, and was disappointed when that didn't happen. Here's a log of the repair of my XBR set.
Local Sony authorized repair center comes to look at my XBR400. "Yep, it's dead" $60 KA-CHING! for this bit of sage advice. They, with my assistance, manage to remove said 240lb TV from my residence.
Two weeks later they call me to inform me that the D-board is toast. Surprise, this fits exactly into what other people have posted about on here. They give me an $850.00 repair quote. I mumble in shock for a while. They tell me $550 of this is for the replacement board.
That night I call Sony technical support and keep asking for managers/supervisors until I get someone with a brain and the authority to actually do something about this situation. (The TV is out of the parts and service warranty) I not so calmly explain that I am NOT paying to fix their defective merchandise. That I will make it my personal quest to sully Sony in the future to anyone who will listen. She tells me that Sony will launch an "inquiry" and do some research into the problem. See, Sony doesn't know what I'm talking about.....  She gave me an email address, to which I sent a url referencing the forum post here about faulty D-boards.
The next day Joe from Sony calls. I like Joe, he seems very reasonable. Joe says Sony, in their infinite corporate generosity, will agree to pay for the parts. He communicates this to the service center. They promptly ignore him and try to charge me the full amount anyways. After a few faxes and angry words things are straightened out.
Now, two MORE weeks later, my TV will be delivered tommorow morning. Hopefully fully functional. Minus the parts and associated tax my tab came to around $250.00.
Plus not having my TV for a month. Sony did take partial responsibility for their manafacturing issue. I obviously would have preferred for them to cover the entire cost of the repair, on what is supposed to be their premier line of TVs. (XBR) However, I was surprised that they budged at all.

I am having the exact same problem. If you can provide that email address or phone numbers it would be appreciated. Also, I have have not found the other threads here (are they archived?) A very frustrating situation

Status update:
With surprisingly little complaining by me, Sony agreed to provide a new d-board at their expense (I am out of warrenty). I have to pay the labor. I gets installed on Monday. I will report back whether this fixes the problem.

My XBR400 just died also. Same thing, light flashes a few times then it goes back into standby mode. I guess I am in for this same fight with Sony over a product that was defective to begin with. I have had this TV for just under 2 years and until now was completely satisfied with it.

My 36XBR400 died last weekend.I've had it since August 2000. No picture, but I still have sound. I have no Sony authorized service centers near me. So I called around to the local TV tech's and nobody wanted anything to do with a late model Sony (they practically fumbled over their words, ssso...sssso...ssony) I did find one guy that is working for himself that does in home service only (he has no storefront) that was willing to take on this task. He came over to look at it. He was really eager to see what was wrong with the tv, for experience. He was VERY knowledgable of tv principles in general, but he wants to figure this one out. After probing the boards for shorts and everything else a normal tv would show, he narrowed it down to the D-board! But he is positive he can fix it if he had the schematic. He will get the schematics this weekend and run his Oscilliscope on the board and isolate the individual componets causeing the problem (hopefully) So I will post back here what he finds and replaces for a fix so that anyone else may use the info. I gotta give the guy credit, he likes a challenge.

Any opinions on what your tv looked like after your new D board? Did the pq look the same?

Sounds like the moral of the story is if you are going for a Sony Wega, spend the extra couple of hundred bucks on the 3 year extendable store warranty. I guess now I'm glad I did!

Update
Sony techs had my XBR400 for 7 weeks. Got it back working but 4 weeks later same problem. It's dead again! Sony has been absolutely useless in helping and believe me I've tried.

My Sony KV36XBR400 TV died (the same problem) last week, after 2-year usage.
Sony service center is scheduled to repair it in August.
Now my concern is not just that I am forced to pay for their defect (even though I already paid >$2500 for the "top-of-line" TV). Will it die again after the >$300 repair? Look, they have only 90 day "warranty" for service.
Any idea? thanks.

My 36XBR400 started dying recently too.
There is a way to force this POS to work which requires about 30 minutes of powering on and off using the TV's on/off button.
If I continuously push the button on and off eventually I get an compressed picture on the screen. When there is motion in the picture, the unit will immediately shut off. As I continue to keep pushing the button, and the TV shuts itself off, I noticed the picture starts getting larger. At a certain point when the picture is almost as large as the screen, the unit doesn't shut off.
At least for me.
I called Sony's CS line and they didn't seem to care at all. They told me there is no issue with this TV, that anything I read online is BS and I've got to shell out my own money to fix their defective TV.
I stopped buying Sony telephones because everyone I've had stunk. I will never buy another Sony DVD player again after my S550 suffered the C13:00 problem. Now after spending $3K on a top of the line Sony TV and leaving me out to hang, I will never buy another Sony product again.

-Can't you sue sony for sellin' very defective, and very expensive electronics? They'll most likely just choke up the 2 thousand or so dollars for a new Tv to avoid too much public attention and if not... well at least you might get some airtime on your local news channel!

After only 2 years, my friggin XBR400 now has no picture, only sound. This after only a year ago having the picture tube replaced. What a POS!!! I'm so pissed at Sony - what a piece of crap TV they put out there...and then don't have the balls to admit it had a defect and help us poor suckers that forked out $2,400.

I purchased a Sony KV-36HS500 this past July. Just 18 days after the 90 labor warranty expired I too got the dreaded "set won't power up and blinking standby light" problem.
I Called 1-800-222-SONY and had service requested for my TV. The gentleman from the Sony authorized Service Company showed up and diagnosed the problem as a failed D Board. The part was ordered on 11/18/03. The board after being backorder is supposed to be in Sony's hand on 12/12/03 and they will ship the board to the authorized repair company.
After the initial call to the 1-800 number I followed up with a second call using the event number I received from the initial call and asked for the problem to be escalated. A manager from Sony called me back within 2 hours, heard my story and said that Sony would to cover the part and labor on this one.
By the time I get scheduled to have the D Board replaced once it is in the authorized repair company's hands I could be without a TV for up to 6 weeks. Is this really a way to run a business?
Sony - The one and only?
Yep, could be the only Sony product I ever own.

Here is my story:
After a year and three months my XBR400 started developing the same symptoms described above - it would quit, I would turn it back on, it would quit, and so on. I called my tech of many years and he came, took the innards of the TV with him and after a few days, he called me and told me that it was the D Board. He ordered a new board and a few hundred dollars later my TV was back in form.
Guess what? Six months later, the TV breaks down again with the same symptoms. My trusty tech comes back and he tells me he suspects the D Board is the culprit again - hauls the innards away and a few days later lets me know that he suspects is such and such component on that board, but that replacing that component alone won't be much cheaper than ordering and replacing the entire D Board again.
After reading the posts here, I called my tech to alert him about insisting on a new board as opposed to a refurbished one. He is of the opinion that refurbished boards are as good or better than new ones because Sony has then had the chance of replacing the defective components that affect other new boards. I suppose that makes sense.
Does anyone have an address where I can send a letter to? I'd like to get a new D Board paid by Sony for when the TV breaks down for the 3rd time - something pretty certain to happen considering the history of some of the problems you have experienced and my own - after that, I'm just throwing it away. Needless to say, this is one person who will never buy Sony again - I just ordered and received my replacement for the Sony - a new 46" Samsung DLP (Digital Light Processing) projection television, fits in the same hole in the wall where I had the Sony and it has a beautiful picture. I'm sending the Sony to my spare bedroom - perhaps it will last longer with less use.
Sony is not what it used to be. The picture of their sets continues to be one of the best, but their quality has already reached Yugo levels.

Add me to the list of SONY owners that have a defective 36" XBR400. I really appreciate this forum. Thank you to all for providing details on the defective XBR400s. Prior to this forum, SONY service and my local high-end video stores were trying to explain that my situation was unique. It is obvious to me that this is clearly a SONY defect that I believe should have been treated as a recall. Based on my interaction with SONY service during the past week, I will NEVER buy a SONY product again. My case has been escalated, but I've been told that they won't do anything since the TV is 3 years old. I don't have an extended warranty.
I think that I too have a defective D board, but will explain the defect on the off chance that it may be something different. Once on, I've never seen the TV power off. The problem I have occurs when the TV is off and I try to turn it on. With increasing regularity, it takes about 20-40 power-on attempts. In reality that is double since the TV requires one attempt that moves the TV to permanent red light (standby). When this happens, no sign of anything related to power-on and no picture. With the second attempt, I see the standby light flash about 5 times and notice an attempt to get a picture. The picture goes on/off very quickly. I cycle through this fun about 20-40 times. After about the 30th time, I notice the duration of the picture extending. So, instead of less than one second, now the picture stays on for 3-5 seconds. It has become a running joke with my children. They count the number of seconds that the picture stays on, knowing that the odds increase of it staying on as we cycle through this process. One day, they'll hate me for this. But I digress. Anyway, once the picture is on, it looks great and stays on.
So, is this a defective d board? If it is, does anyone have recommendations of the best way to replace it. I'd like to call someone that understands this and knows how to fix it rather than deal with service call charges from Yahoos that don't have a clue. If you know of a technician that you recommend, let me know. I was even thinking of trying to purchase a d board and doing the work myself. Sounds like I may have to do it 2-3 times anyway, so why not learn how to do it.
In addition, if anyone has contact info at SONY that you recommend I write to, please let me know. I paid $2,400 for this POS because I assumed I was buying a great product. This defect should have been recalled. My plan is to start with the President of SONY U.S.
Thanks for your help.

Put me on the list of D boards as well. My XBR was about 1 year and 11 months old. Starting losing vertical hold, then finally the set would go out due to high-voltage issues. My service center came out and I was around $700 parts and labor. Luckily, the part was available. Now I'm fighting with Sony as I think spending this much on a "new" "high-end" TV is ridiculous.
If you're someone that's had a D board go bad, could you please contact me via email? I'd like to start compiling a list of people and see what we can do about this.

My 36XBR400 just died after 3 years. I paid $65 to be told "yes, your D-board is bad, and it will cost $400-$500 to fix." I called Sony, and of course they are not interested in helping me since it is 3 years old. I pushed and they agreed to call me back, but I doubt that will happen or go any where. The rep. mentioned an exchange program, to where I get a different new Sony model, they get my piece of junk XBR400, and I pay a lot of money. They would not give me specific cost - the guy has to email the exchange people and then get back to me. Has any one here had luck with the exchange program, or is it a rip off? I am leary of spending $400 - $500 on a defective tv that may fail again in a short time span. Thanks for any thoughts.

Basmith,
Take a look at my post a few above yours. It seems we had the same problem.
I was able to get my TV to start up faster quickly switching from a channel with a signal to one without a signal like a game input. This seemed to allow the TV to "warm up" without it shutting off immediately.
Don't know what kind of long term damage you might be doing to the TV this way but at least it turns on.
I basically wrote off my 36XBR400 and gave it away. Bought a new Panasonic 50LC13 and have sworn off Sony FOREVER.
Here's another Sony problem thread for your amusement. Its for their top of the line Grand Wega III. It seems Sony hasn't and will never change.

I Live in Downingtown and was just told today that I need a whole new chasis for about $1,000. Another service man told me I needed a board that will cost about $450. I will be in touch with sony folks tomorrow. My KV-36XBR400 is 2 years 9 months old and while I love the picture I can no longer turn the set on. I get the 5 flashes no picture or sound. When it first started I had to try 10-20 cycles of on off before it would power up. While the Eagles were in the playoffs I never shut the set off. After the miserable loss to the Panthers I shut it off and has not been on since. I also want the e-mail or phone number that was used to get the partsfor free. Please post for all thanks.

Hello everyone! I'm having the same problem as sanbee. LED/Standby continuous blinking red light 5 times. I've been able to power cycle the 36XBR450 successfully twice and just left the unit turned on. A couple of months later the unit just shut off. Now I can't get it back on no matter how many time I power cycle this. From all of the postings there seems to be allot of talk regarding the infamous D-board. Has anyone with this symptom been able to determine if it was a defective D-board or simply a defective CRT?
Thanks again on any input you may have.
Ed.
p.s. Sign me up for the defective D-board list as well. Thanks

I'm sure someone somewhere is organizing a lawsuit against Sony regarding this issue. There's just to many of us with this problem. Please let me know if anyone knows of any class action suit in the works. I want to participate!

If you are interested in attempting to fix your XBR400 yourself or you have a friend that might be willing to do the work for you, I suggest that you checkout http://www.fixyourowntv.com. Good luck!

Looks like my D-Board is failing as well. Had the TV for 3.5 years now it takes 10 mins to finally get a picture after powering on/off numerous times. Got an extra 2 year Sonycare warranty, but I guess it wasn't enough. I'm going to try talking to Sony to see if they can rectify the situation. I love Sony products expecially the XBR and ES line, but this TV may make me jump ship.
Does the 36XBR400 come with a 1 or 2 year standard warranty in Canada?
Thanks!
Bill.

And I too have the infamous D-Board problem. Specifically, I am told my two poteniometers are out and it requires replacement of the entire board.
Being out of warrenty I was told the board is over $400. I refuse to pay that. I called Sony customer service and they were most unhelpful. In fact after the first person patched me through to her supervisor I was told that there was no one else I could speak to and then was told that there was no one to whom I could write a letter or email to!
Well, that wont do!
I have written a letter to:
Mr. Nobuyuki Idei (Sony top gun)
C/O Sony Corporation
6-7-35 Kitashinagawa
Shinagawa-KU
Tokyo 141-0001 Japan
Mr. Hideki Komiyama (Sony US top gun)
Sony Corporate Headquarters
attn: Office of the President
1 Sony Drive
Park Ridge, NJ 07656
Mr. Howard Stringer (Sony Electronics US top gun)
same address as above.
I wish I would have found this site before hand because I would have included printouts of this thread. Sorry folks. Maybe the next person will.
My letter is as follows:
I know you are busy and I won’t take much of your time, however this is something you may want to hear about. I purchased my Sony Wega XBR 36 inch TV a few years back for almost $3,000 believing it to be a quality, long lasting product. A few months ago this product stopped working and it turned out to be a common problem (according to three authorized Sony technicians) with the high voltage side. Specifically, with RV 8001 and RV 8003 on the circuit board. These parts are not sold by Sony individually and require the purchase of the entire board at a cost of over $400. This was in itself amazing to me, especially considering the fact that this is obviously a design fault and was even called such by your authorized repair technicians.
ffice ffice" />>
>However, even more amazing to me was the response of your ‘customer service’ representatives. My phone call to your company was first handled a nice lady who unfortunately couldn’t say anything more than, “oh, I see. Ok, well is that all?” I asked to speak to her supervisor. Her supervisor Anthony belongs more in a collection agency than talking to paying customers. His only response to me was basically that the buck stops here and that he makes the decisions. We won’t do a thing for you and there is no one else who will talk to you. He stated his boss is in administration and does not talk to customers. I asked if I can send a letter or an email. No, we do not give out addresses and do not accept letters or email from customers. Yes, he said that!

>Sony, even more discouraging than the poor quality XBR I bought was the response to my plea for help. I have always been a Sony fan and my list of equipment would span pages and tally into the tens of thousands of dollar range. I realize that to your company this is small potatoes, but at the same time I am sure you realize it was, and still is the individual consumer who still keeps the dollars coming in to your company.
> >I don’t know what, if anything, you can do at this juncture to make things right and after my talk with Anthony, it seems that you all may not even want to make things right. In today’s business climate I find this quite discouraging. After all, Sony is one of the greatest, most respectable Japanese companies out there and if this keeps up then what, will we all be buying Korean electronics? What brand TV shall I buy to replace this one?

First time poster here!!
I also am encountering the same problem as everyone else here on this thread, my just barely 4 year old 36XBR400 just lost it's picture but only sound last week, and today I got a call from the TV repair (sony authorized) that my D-board is bad and it's going to cost over $500 not including delivery..
My wife bought this TV for me for my B-day, that $2400 was not worth the spending, I am watching a back up 15 yr old mitsubishi..
Sony's customer support was less than helpful, they said their authorized repairman was on a sick leave and they recommended me to a few local authorized repair shop, but they said they couldn't guarantee the repair cost.. what kind of b.s is that.. I'm fed up w/ Sony!http://www.agoraquest.com/images/forum/icons/icon_mad.gif
If there's a joint lawsuit reguarding this matter, add me to the list, if any of you got reinbursement from Sony, please email me the info, Thanks!

I also had a D board go bad on my KV 32XBR400 (little over a year old)and luckily had bought the circuit city warranty so I was able to trade up to the 40XBR800 for 700 dollars more. Today I just placed a service call again for my 40XBR800 because of the "color blooms" or "impurity" that have plagued the lower section of my TV. *Sigh*

Based on my 3 years experience so far (luckily I have a 4 year extended warranty), we are dealing with at at least three different problems:
<b>1. XBR400 does not come on.</b>
It clicks, but you never hear the magnetic hiss. A few seconds later, another click, and back to standby.
I am presently leaving my set on standby all the time (my wife loved to turn it OFF (at the set) to save energy). I also have it on a dedicated outlet, to make sure it gets enough startup juice.
Only a few days, but still working.
<b>2. XBR400 turns on, and then goes off after 10 to 30 seconds.</b>
I had that one when I received delivery of my (floor model) unit, and the store (pacific sales) replaced it with a brand new one. So, I enede up with a new set at the price of the demo unit.
<b>3. Sound, but no picture</b>.
I do not have this one (yet) and assume it is something different.
4. But then of course, there is the white line flash (and zapping noise) across the screen. This actually went away after almost two years, just as the tech wanted to get a new tube. He suggested it was arcing away some residual stuff on the cathode.
Have not had another incident for a year now.
I'll be reporting back if problem number 1 happens again, or not.

Well, that theory did not work either.
It was working for a few days. Now it will not come on at any time of the day.
Fortunately, I have a 5 year 100% warranty, that was included free of charge when I bought the set in Dec 2000, at Pacific Sales. Good move.
So, I called my GE warranty people and they are sending the technicians from the "Good Guys", on Thursday.
Will let you know what happens.
It took him just 5 seconds to figure out he needs a D_board.
That will be another week, but at no cost.

All I can say is that Sony Rocks!
After the letter I wrote in July I got a call within a week from some stealth customer service unit which offered to fix or replace my set. Not wanting to have the D-board crash on me again I opted for the replacement program thinking that well, at least I'll get a small rebate or something toward another set. After all my XBR was 4 years old and out of any warrenty.
Well.... They offer to give me a 32HS420 which sounded great to me. A month went by and no TV so I called them back and they were super apologetic and promised to get me a set within a week and since the 32HS was not available they will give me the 34" version of that. A week later they call me back and say that sorry, that one is not available either so I have a 34XS955 on the way!
It arrived yesterday and I am so pleased with Sony, I simply cannot belive that I got this TV in exchange for my old 36XBR400. Even though it is a bit smaller the HD and widescreen more than make up for it.
LOVE IT! Thanks SONY!!!!!!! !

Be glad you got the XS. It has the fine pitch tube which makes better use of the HD signal. Maybe if you had stuck it out, you would have ended up with an XBR960!!

Does anyone have names and numbers of SONY people who can help with the d-board problem in terms of getting them to at least pay for the part????
my orginal post
 Posted: 2004-10-02 15:05
I have an KV32XBR400 No Power on- Standby LCD Seven Blinks. For the last few weeks I have had this intermittant problem which seems to be getting worse. The set is plugged into a power strip with a 400v surge protector (there are no other ratings on the protector it). I have read some of the older posts and have unplugged the set for several hours and then restarted it, sometimes it works sometimes it doesn't. I have NEVER had the problem of the set just shutting off by itself.
Since I have had the set I would sometimes notice "static pops" and a slight green horizontal line. Does this have anything to do with the power problems???
In addition, for some reason this power problem happens when the I shut off the TV on Video 1 one???
I called a New York City- SONY authorized ( Advisory TV). Quoted about $250 for a new power supply and $250 labor , is that what other people have paid? They are not coming for a week, so if I'am able to get my set turned on again can I leave it on for a week ??
Also, I can access the service screen will it give me an addtional information which would help diagnose the set in addition to the seven blinking lights??
This is my 3rd xbr and the other 2 have had power problems also. Great site, wish I found it years ago...

No one has come to my rescue since my initial post but thought I would pass my experience along. If I leave the TV unplugged for several weeks (or months) and then plug back in it will turn on and work perfectly as long as not turned off again. Three times this has happened until accidentally turned off using VCR or DVD or cable box remote. Next time I get it to power up I am leaving it on 24/7 and covering the remote sensor!

I suggest that you do not turn the set off again until you get it fixed.
I did that one time too many, and it never came on again.
Fortunately, I have a 5 year warranty with GE-Zurich. Unfortunately, they use the good guys (should be the bad guys).
The technician immediately figured out that I needed the famous D-board, and told me that he would be back in less than 7 days.
7 weeks later, after several complaints to state agencies, he finally came back and replaced the D-board. Works fine now. If I had not turned the set off that last time, I could have watched it for the last 7 weeks.
From now, I would not go to the Good Guys for anything.
As to the static pop, with green (or white) line, I had that too, and it went away after two years. Supposedly, it is the Cathode cleaning itself from impurities left behind from manufacturing. Another indication that Sony quality is not what it used to be.

I posted a message 3 months ago about the problem w/ the D board on my 36XBR400, I had the D Board replaced by a authorized Sony repair (3rd party), almost right to the date of my repair warranty (90 days), it has clunked out again!!! Now not just the symptom of sound w/ no pix, now is just no sound and no pix.... I'm so fed up w/ this... Wondering what I should do.... This crap's got to stop!

Seems I have the same problem except that I also have a color issue. The screen took on a redish hue, as if the "red" in the color settings had been cranked way up.(of course, I checked it and its in the correct position). My xbr400 is almost 4 years old. The Circuit City extended warranty ran out a year ago.
I "reset" the tv by unplugging for 30 minutes. Turned it on and it was ok for about 3 minutes. Then it went "red" and then shut off after about 5 minutes. Except for the "color" issue it sounds like the same problem everyone else has. Granted, it cost me $2400 but it doesn't sound like its worth the money and hassle to get it "fixed". Maybe its best to bite the bullet and get a new one. Maybe that's what Sony wants us to do?

A competent technician may be able to fix your problem without resorting to replacing an entire circuit board. I would contact my local authorized Sony servicecenter and get an estimate first. Who knows! You may be surprised!

If you look in the yellow pages under "Television Repair", there is only one SONY AUTHORIZED FACTORY SERVICENTER listed, ROSS FACTORY SERVICE INC. I would give them a call. I have no idea how good they are, but that's the only place that I would consider because it is an authorized Sony servicenter.

Tried to turn on the 32XBR400 today and it won't. The standby light blinks slow ~6 times, then fast for a few seconds, then slow again ~4 times and the TV powers off. It never gets far enough to have a picture or sound. I've had no problem like this at all before today and the TV is just over 3 years old.
I have read all the details here and it sounds like I have the "D Board" problem. I went to the Sony Online support site to arrange for In-Home service, entered information about my model, indicated I am out of warranty, and a response page loaded talking about a "Flat Rate Program" where they charge $290 to fix the set plus a $60 trip charge. The page says that some big items (e.g. the Tube) are excluded. Additionally the page said that if the fix is not covered, they charge $26 for dignostics and give you a quote for the fix. My questions are:
1) Has anyone used this "flate rate program" to fix this problem? In San Diego?
2) Is the D-board covered under this flat rate?
3) Is there any chance they will come out with a replacement D-board and install it at my house?
Barring any of this, I may try Mycrobytes' approach and write the senior management of Sony. Has anyone else tried this? The drawback here is that I am without a TV for many weeks I guess.

Three days after I bought this tv four years ago its started to show exactly the sysmptoms you guys described. I called Good Guys to tell them what's happening and the sales guy told me he will sent a replacement in a week. Four guys showed up in my house including I think their store manager to check it out (highly unusual if u ask me). So I showed them and then this manager told me that I am the 8th Cx to call about the same problem.
Well this replacement set has been chugging along. No problem whatsoever. I believe that I have been very fortunate.
Sony "does" know about the problem happening on some of the sets. Unfortunately for some of the Cx the symptoms appear after the Mx warranty. I personally think that they should have issued a recall to replace the defective parts. Its verrrrrrrrrry unfair for us to pay hundreds of dollard for something not caused by the user.
If we all raise a stink they probably would recall,replace or reimburse us for all the trouble it caused.

I have a post with a similar problem....sound but no picture with my 4 year old kv-32xbr400. Here is something to try as a temporary solution. This works for me, hopefully it will for others. Turn the set on and let it warm up for 10-15 minutes. Shut it off with the front panel switch, unplug it for at least 60 seconds. Plug it back in, turn it on. This has worked for me every time. At least we have the tv to watch as I try to fix the damn thing.. Hope this helps someone.

I am looking to buy a used 5 year old 36XBR400 set and decided to read up on the TV and of course came across all these posts. My question is, has anyone been provided a permanent fix from Sony? Or should all XBR400/450 owners expect this problem to occur more than once as long as they own the set?

I was given a free KV-36XBR400 last week with a shutdown/blinking code failure. I was a TV repairman in the 80s and 90s, but quit about 5 years ago when it got to be that most people would rather buy new than repair. This was the case with this TV... The customer laughed when the shop gave a preliminary quote and told the shop to dump the TV. It shuts off after a few minutes and blinks the LED 7 times, pause, and 7 more until I pull the plug. Then I can turn it back on and eventually it will stay on. The B+ is regulating beautifully at 135.0, but I notice that the scan is about 1/2" shrunken horizontally. Obviously these are related. I don't have the schematic for it yet, and I am REALLY curious what that blinking code points to! I remember reading that the deflection yoke is a problem on these sets, and that could in theory cause a horizontal shrink and overload on the sweep circuits to cause shutdown. If it's on the deflection (or "D") board, it is most probably a leaky capacitor or a failed regulator chip. People here are talking about "replacement" D boards, but that is silly when you can repair. Motorola tried that "replace board only" thing in the 70s on their Quasar TV sets, and it was a disaster. Motorola never recovered from that fiasco and eventually sold the Quasar name to Matsushita .
If anybody here knows the definition of that 7-blink code, please post... Otherwise, I will troubleshoot the board when I pick up the manual and will (hopefully) post my findings. I do not believe in replacing complete boards!!!!!!!! I always did it the old fashioned way by troubleshooting and replacing discrete components. How about a 30 cent capacitor in stead of a $400 D- board!!! Are the Sony factroy techs being LAZY, or just INCAPABLE of an old-fashioned troubleshoot?
Just one more MAJOR point: If you get 3 or 4 years out of ANY late model TV set, you are doing great (Sony or any brand)! These aren't what they were in the 1960s and 70s when you could expect 30 years. Most 1960s and 70s TVs such as the 1970 Sony KV-1710 or the Zenith Titan series Chromacolor sets are still working.... just as they were when they showed the Nixon inauguration live. On the other hand, most '90s TVs are decomposing at the bottom of landfills. There is also a pile of plasma TVs at a shop I used to work with, and they are REALLY nonrepairable. Buyer beware!!!

Followup:
I still have not troubleshot the original D board, because I got a used one for $10 and now the KV-36XBR400 is working great! I did have to make some raster geometry corrections, as the picture was bent slightly. Otherwise, the job was a simple plug-in.
The trouble code of 7 LED blinks is shown in the service manual as being a horizontal sweep failure. This is a vague code, because just about any component on that D board and some on the signal board could cause it! Kind of like the "CHECK ENGINE" light in those dumb Gasoline-powered cars that can mean anything from a loose fuel filler cap to a failed cigarette lighter...

just a tip about this POS. I've observed the on-off game mentioned earlier in the thread as working pretty well when the weather is warm, and the house is stuffy. It take as little as a few clicks on-off. In the winter time, forget about it, it's the most expensive paper weight every conceived.
Further, a technician on another message board noted that he can get this POS to turn on if he heats up the D-board.

Okay, add my 36XBR400 to the list. Sound but no picture. I worked my way through college selling Sony when my coworkers were selling Mitsubishi because it put more money in their pocket. My 36XBR400 is about 4 years old and probably not worth fixing. Customer service was worthless! I will try to send a letter to the president of sony as one poster did before. Looks like it's Hitachi or Panasonic from here on out unless Sony will help me.
Wish me luck, my fingers are crossed.

just to follow up on my earlier comment about heat....
hitting the d-board with the blow dryer for a minute or two, and very little problem getting it on with the on-off game.

Hello all, I have a question, I recently acquired a KV-36XBR400 Sony TV. One of the circuit boards is missing, if I can determine which board is gone can I purchase a new one or will I have to find one used? Thanks

Very interested to hear whether anyone has taken this particular issue(s) a step further with Sony and their seemingly infamous defective "D" circuit boards?
I find it verry troubling to have paid as much money as I did, which was nearly $2500 for this 32" Sony TV, to have it only last a couple years before going south on me.
Just out of warranty, and the people I'd talked to after calling Sony's 1-800 number were not of any help, ...in fact, they denied there ever was any kind of problems with their TV sets and "bad" D-boards. Needless to say, I'm very PO'd, and would like to pursue this any way I can. I WILL NOT STAND FOR THIS FROM SONY!!! Not a chance!!
Any information would be greatly appreciated!!!!
Thanks!!!

Hello everyone! I'm having the same problem as sanbee. LED/Standby continuous blinking red light 5 times. I've been able to power cycle the 36XBR450 successfully twice and just left the unit turned on. A couple of months later the unit just shut off. Now I can't get it back on no matter how many time I power cycle this. From all of the postings there seems to be allot of talk regarding the infamous D-board. Has anyone with this symptom been able to determine if it was a defective D-board or simply a defective CRT?
Thanks again on any input you may have.
Ed.
p.s. Sign me up for the defective D-board list as well. Thanks

Put me on the list of D boards as well. My XBR was about 1 year and 11 months old. Starting losing vertical hold, then finally the set would go out due to high-voltage issues. My service center came out and I was around $700 parts and labor. Luckily, the part was available. Now I'm fighting with Sony as I think spending this much on a "new" "high-end" TV is ridiculous.
If you're someone that's had a D board go bad, could you please contact me via email? I'd like to start compiling a list of people and see what we can do about this.
I Live in Downingtown and was just told today that I need a whole new chasis for about $1,000. Another service man told me I needed a board that will cost about $450. I will be in touch with sony folks tomorrow. My KV-36XBR400 is 2 years 9 months old and while I love the picture I can no longer turn the set on. I get the 5 flashes no picture or sound. When it first started I had to try 10-20 cycles of on off before it would power up. While the Eagles were in the playoffs I never shut the set off. After the miserable loss to the Panthers I shut it off and has not been on since. I also want the e-mail or phone number that was used to get the partsfor free. Please post for all thanks.

My KV32XBR400 died on me, called sony authorized service and was told that the high voltage something blew.Would cost $450 to fix the problem.I tried calling sony but to no avail.I had the TV hooked up through a Monster Power surge protector and have other units like Marantz dvd and Nakamichi reciever also hooked through the same.They are working fine.Im more angry at the sony's dont care attitude.The Customer care doesnt even try to listen all they asked was when did you buy it and it is out of warranty.Im planning to contact the Better Business Bureau and the NY state attorney generals office for consumer complaints.After spending $2,300 for a TV I expect it to last more than 3 years.And after going through different forums I understand that this is a very common problem with Sony.I wonder the Sony Head Office in Japan knows about this.Well if any one else has tried any legal action please let me know.
Thanks
I have around 9 different sony systems in my home and computers at work.Now I have to change my brand to some other company....I had this LG product and Im really satisfied with their Customer care!!!!!

Has anyone got information on how to fix an 36xbr450 - bought 3 years ago, fine shape and the blinking light on TV flashes 5x's and turns itself off? Is there any type of recourse for the consumer with these products? What does the law state in NY in regards to assumed liability for the consumer vs. the manufacturer/ distributor when purchasing a major electronic appliance from a supposedly reputable company like Sony? I've gone through the trouble shooting and had a service person come in and look at the TV and said it would be minimum of $500 to fix a defective D board- so you spend $2000, then another $500 to fix after 3 years of use? Makes no sense- if anyone knows of whom to contact at the Better Business Bureau in NYS or the AG's office that would be very helpful-
Thanks
Pete

Welcome to Agoraquest! Replacing the D board is a quick way to make a repair. A tech that actually takes the time to troubleshoot the problem can determine which component(s) on the board need to be replaced. But then there is a tradeoff, hourly rate to troubleshoot and repair plus parts or hourly rate to replace D board plus cost of D board. Anyway, the part number for the D board required is A-1346-948-A. The retail price to you is $243.93. The dealer price is $203.74. You may purchase it yourself at the retail price here. Just search for Part or Accessory Number a1346948a.
As far as the life of the set, I purchased mine 3 years ago too. I am holding my breath! These sets are quite complex. You would probably would have similar problems with equivalent sets. The problem is that there is no equivalent to the KV-36XBR450 by another manufacturer.

I was given a free KV-36XBR400 last week with a shutdown/blinking code failure. I was a TV repairman in the 80s and 90s, but quit about 5 years ago when it got to be that most people would rather buy new than repair. This was the case with this TV... The customer laughed when the shop gave a preliminary quote and told the shop to dump the TV. It shuts off after a few minutes and blinks the LED 7 times, pause, and 7 more until I pull the plug. Then I can turn it back on and eventually it will stay on. The B+ is regulating beautifully at 135.0, but I notice that the scan is about 1/2" shrunken horizontally. Obviously these are related. I don't have the schematic for it yet, and I am REALLY curious what that blinking code points to! I remember reading that the deflection yoke is a problem on these sets, and that could in theory cause a horizontal shrink and overload on the sweep circuits to cause shutdown. If it's on the deflection (or "D") board, it is most probably a leaky capacitor or a failed regulator chip. People here are talking about "replacement" D boards, but that is silly when you can repair. Motorola tried that "replace board only" thing in the 70s on their Quasar TV sets, and it was a disaster. Motorola never recovered from that fiasco and eventually sold the Quasar name to Matsushita .
If anybody here knows the definition of that 7-blink code, please post... Otherwise, I will troubleshoot the board when I pick up the manual and will (hopefully) post my findings. I do not believe in replacing complete boards!!!!!!!! I always did it the old fashioned way by troubleshooting and replacing discrete components. How about a 30 cent capacitor in stead of a $400 D- board!!! Are the Sony factroy techs being LAZY, or just INCAPABLE of an old-fashioned troubleshoot?
Just one more MAJOR point: If you get 3 or 4 years out of ANY late model TV set, you are doing great (Sony or any brand)! These aren't what they were in the 1960s and 70s when you could expect 30 years. Most 1960s and 70s TVs such as the 1970 Sony KV-1710 or the Zenith Titan series Chromacolor sets are still working.... just as they were when they showed the Nixon inauguration live. On the other hand, most '90s TVs are decomposing at the bottom of landfills. There is also a pile of plasma TVs at a shop I used to work with, and they are REALLY nonrepairable. Buyer beware!!!

This post is great - I can't believe so many people are having the same problem with their 36XBR400 as I had.
Mine is working now, but here's what I went through.
Suddenly one day the TV just stopped working no picture, but had sound. I took a quick look myself to see if a fuse was blown or something and then called a local service guy who came in and charged me $50 to look at the TV for 2 seconds and say I needed a new D board.
I would of called Sony and bitched, but thought my D board was the exception to the many good ones out there. Anyways the service tech said the D Board was $600 - I ordered one from Parts Place or something like that for $350 and popped it in myself. It worked for 12 hours. Thankfully they let me return the part and I got refunded for everything except the shipping - I think that board was refurbished.
Next I brought it to a local Repair Shop - who diagnosed it with a scope and replaced a transistor ... $300 for diagnostics and $15 for the Transistor.
It worked for 2 weeks and died again.
I took it apart thinking I could find the faulty transistor on the D Board ... no luck, but I found the manual online. http://www.eserviceinfo.com search for the DX1A chassis. My Sony was blinking 5 times - it told me to adjust the G2-VR FIrst Left Then Right Bingo - It's Working.
The service technicians are getting lazy just replacing the entire boards, plus if anyone else's is blinking 5 times the G2-VR is on the C board replacing the D won't do anything.
Note of Caution BE CAREFUL if you look at this yourself there are VERY HIGH voltages inside the Chassis.
Good Luck

I dispute the notion that “service technicians are getting lazy”. Manufacturers refuse to increase labor rates. A large percentage of customers have service contracts, which set flat rates for labor. The remaining few act like you are taking food out of their children’s mouths when you give them the labor estimate. So naturally we are going to spend the least amount of time possible on each repair. If the repair is going to involve a large amount of time, we may just recommend replacing the entire board. fficeffice" />>>
As for your situation, look at the larger picture. Almost all Sony directview and projection sets have “D” boards. But they are different from each other. The “D” board creates high voltage and convergence. These are the two most power hungry functions in any set. So where do you think the most failures are going to occur? >>
Too many people seem to think they are entitled to failsafe operation for ten years. Tv’s break! We see most major brands and Sony’s are no more prone to failure than any other. We replace the same types of parts in the same circuits for all brands. >>
>>
Treat you technician kindly, he is an endangered species.>>

Yeah, so I'm wondering if anyone can give me the information as to where I can purchase a new "D" board for our 32" Sony Trinitron. I'm looking for the least expensive board available, if possible.
We'd purchased a repair kit from Dakota, however, that didn't seem to fix the problem. By no means am I "bad mouthing" Dakota or his repair kits, as he seems to be a "stand-up" guy, very helpfull, and yes he's an endangered species. I'm simply stating that the repair kit didn't work for us. We have the same exact issues as before the repair kit was installed.Tried the hair dryer trick that another forum member had recommeded, but no dice.
Please advise.
Thanks!!!

What is the model number of your 32" Sony Trinitron? Who knows? The cost of a new D board from Sony might be less than for a KV-36XBR450.

Sorry, I guess that would help. It's a chassis model DX-1A "KV-XBR400"

Wow! The D board for the KV32XBR400 is a whole $2.43 less expensive than the D board for the KV36XBR450! BTW, the same D board is used in both the KV36XBR450 and the KV36XBR400. You may order the KV32XBR400 D board here for $241.50 (USD) here. Just search for Part or Accessory Number a1346947a.

I having the same problem with my KV36XBR400. Red light blinks 5 times, turns itself off, nothing happens. Started about 3 weeks ago. I opened the back, cleaned the dust out and downloaded Sony-DX-1A TroubleshootingManual-OK.pdf. It's pretty good but lacks schematic level information. I was going through the power supply troubleshooting making a few measurements while cycling power over and over. At one point I was trying to measure the 135V and while touching the test point heard the presence of high voltage, that familiar crackle. (That got my attention real fast.) The set started working all on its own. That lasted for about two weeks, then dead again. But Saturday morning it came back on. I turned it off and it has not worked since.
So what I have gathered from this is:
1) It's not a hard failure, something is out of adjustment or there is some sort of bad connection.
2) Adjusting the G2-VR potentiometer on the C board has no effect.
3) The 3.3, 5 and 9V on the A board are fine.
Curious point, I measured -148V on Pin 8 of IC6501. I checked it three time just to make sure I was not missing a decimal point or "mv" indicator. That can't be right, ignoring the negative voltage, 148V on the 15V line would blow a lot of stuff everywhere. I was using the shield of the fly back for my reference, it seemed that it was connected to "E". Can anyone recommend a good ground reference?
One last question to the forum. If I bite the bullet and buy a D board, what is the probability of success and being done with this adventure?
Can a brand new one be acquired or are we stuck with refurbs, aka someone else's problem?
thanks,
john

Usually the chassis is the ground reference.

well, i too wrote a letter to sony executives. after about 10 days, i got a call saying that they would be willing to HELP with the repair cost but would need 2 things;
1. proof of purchase
2. a written estimate from a authorized servicer - i got a quote and since this tv is a tank, i cannot take it to the shop and for them to cme out would cost $225.
sony said they would be willing to provide the D board but i would have to pay for the labor cost. at this point, i am not willing to pay the $225 + the labor cost (~$200) for a fix that i can't even be sure will last. this is quite ridiculous for a few reasons;
1. this is sony's defect. they should cover ALL costs
2. in my letter, i detailed the symptoms and even pointed them to this thread. we know what the problem is, yet they still want me to spend $225 on the repair estimate?
3. why would i spend ~$425 on a repair that i don't even know will completely fix the problem? a new 30" phillips HDTV will cost me $300 shipped!!!
i've been a loyal sony customer for over 10 years. but with this last experience with their quality as well as rude and hostile customer service, i think i will be avoiding sony like the plague for years to come. hope others have better results.

It seems I am having the same problem with my KV-36XBR400 as everyone else. I lost the picture but still have the sound. When I turn on my TV I get the 5 blinks on the stand by light. I adjusted the G2-Vr but it didn’t help. I was reading the manual that was suggested in some earlier posts and it states the C board should be replaced. Did anyone have to do this or is the D board usually the fix? I would appreciate any feedback. Thank you, Ken

I am having the same problem with my KV-32XBR400 where when I turn it on the standby light flashes 5 times and then the set turns itself off.
The Sony Canada Customer (dis)service rep I talked to was more useless than a weasel in a cardboard shirt.
My set was manufactured in July2000, so it is no spring chicken, but I shouldn't have to fork out $400+ to fix what appears to be a defect with this Sony product.
That's it for me and Sony. It is public knowledge, and no surprise, that they are in some financial trouble due in large part to the (poor) quality of their products.

Count me in as another victim.
Started doing it yesterday, a month after my super-dooper extended warranty expired. Of course.
Yesterday it started with not wanting to power on the first try. Worked fine after the second or third try.
Today it just powers on, screen is blue, changes to green within a few seconds and blinks off. Tried turning it back on 30+ times with no improvements/success.
I assume this is the classic D-board problem.
No idea what to do with this boat anchor. I doubt the garbage men will be willing to take it out with the trash?

Here's my story...
I bought the KV36XBR400 around winter of 2000, and it's been working flawlessly up until maybe 2 months ago.
First symptom was the "sound but no picture"...after a power off and on it would fix itself. This usually happens when I turned the TV off and left on standby overnight.
TV was still working yesterday afternoon. Turn it off to do some cooking, and came back to the dreaded 5 blinks standby. So, I came online to find out what was wrong with my television, which led me to this thread. I was not about to spend $400+ (as many of you guys stated) to repair my television, and risk having it crap out again in the near future. We were ready to trash it and hop on the plasma bandwagon...
Today, as I was searching for a new television, my parents decided to call some local television repair guy they found in the Chinese newspaper and decided to give them a call. The guy was willing to come over today (Sunday), and give us a free estimate. Heck, why not right?
Within 3 hours...he was here taking apart the television. Not sure which board he worked on, but it was on the left side facing the back. He did some readings with a transistor tester I believe, and took him no longer than 5 minutes to figure out that a chip on the board had crapped out. He said it would cost $150 to get it fixed and guaranteed to work for at least 6 months, and he would come back if there was any problem. I guess it was a common issue with the XBR400 because he had a spare chip and was able to start working on it immediately. Not too shabby.
He did some more readings with the transistor tester and started soldering the front and back of the board. Took out a metal L shape piece, replaced the chip, more soldering and he was done. The defective chips reads "SHINDENGEN" "MCZ3001D" "00406". Within 25 minutes the TV was up and running again! Paid the guy 150 bucks, tipped him a few bucks, and a Nestea for a job well done.
Sorry for the long post! Hope this was helpful for you guys!
I'll keep you guys updated if anything happens (knock on wood).

Believe it or not, there are three MCZ3001D chips in the set. One on the A board on the right (IC6001) and two on the D board on the left (IC6501 and IC8002). Its anyone's guess which one he replaced.

Same problem as descibed here, the tech is asking for $500 (didn't even mention D-board), said some about powersupply and two regulators. But warranty the work for 6 months....
what say should I try him?

That's entirely up to you. If a $500 expenditure is no big deal for you, go for it! Personally, I would read through this thread and try some of the ideas mentioned.

You can add me to the list too! My KV-36XBR400 worked fine for the first 2 years, then the week after the warranty ran out it started this intermittant ballooning out crap. At first, it was only about once a week... watching a show ...the picture expands, fades to black...click off. All I had to do was wait a few minutes and turn it back on. I put up with this crap for 4 years until now it won't turn back on. I've tried everything mentioned here and actually got it back on one time. We left it running 3 days until my wife forgot and turned it off one night. Now I can't get it back on again. Responses from the TV repair places have been from "I won't work on those...", to "there's no such thing as a new D-Board, I'll have to send yours off to be re-worked and hope it's OK on the first try". If there is a lawsuit about this, someone please let me in on it. I'm writing my letters to Sony today.

Ditto for me too !
I am going to send my "D" board out to be repaired. I found a company in Indiana that will repair mine for $149 bucks . Before I use the set as a boat anchor I will try this fix first. If this does not solve the problem , I will go to another manufacturer for my next TV purchase .
I can see from all the posts that this known problem with th "D" boards is quite an expensive fix and you may want to try to do the same.

Here are details on a successful KV-36XBR400 D-Board repair. Hopefully this will help other XBR400 owners.
My TV began to have power on problems but, initially, I could get it to work by pressing the remote's power on/off button over and over again. When the TV would not turn on, the standby indicator would blink 7 times and stop. This was non-repeating code and, per forum member BUDMAN, did not represent a diagnostic code. Over the span of a couple of weeks the 7 flashes progressed to 6 flashes before settling in at 5 flashes.
The TV became progressively harder to power on and finally it wouldn't not turn on at all.
Before attempting the repair I considered the following options.
- Purchase of a D-Board repair kit from fixyourownTV.com
But I wasn't sure that my D-board was causing the problem. (The repair kit was about $100.)
- Send my D-Board to tristatemodule.com for repair
I seriously considered this option. But, again, I wasn't sure the D-Board was the problem. A D-Board repair would have run about $150 plus shipping both ways. The customer service representative from Tristate suggested that I send in all of the boards to maximize the chances for finding the problem.
- Purchase a replacement D-Board through Sony's exchange program
Again, I wasn't sure the D-Board was the problem and the $243 board replacement cost was pretty steep.
- Pay for local repair by an authorized Sony service center
I never seriously considered this option since the estimated $400 repair cost was more than the cost of a used, but working, replacement of the same exact model.
Finally, I decided to attempt a repair based on other successful repair stories found online and the advice of a Sony repair technician.
The helpful Sony technician told me that KV-36XBR400 "power on" problems often involve one of three MCZ3001D ICs:
IC8002 (D-Board)
IC6501 (D-Board)
IC6001 (A-Board)
These are the same three ICs that forum member jehill mentioned above.
I found the ICs for about $6 each on eBay.
I first replaced IC8002 and that had no effect. Then I replaced IC6501 and the set has been working perfectly for over a month now. (6/1/2009 Update: The TV is still working perfectly well over two years later.)
The IC6501 is also mentioned in a Sony Service bulletin that forum member jehill can send to Premium Members that request it. See the following thread for more information:
http://agoraquest.com/viewtopic.php?topic=26985&forum=34&keyword2=electronics
If the IC6501 replacement did not fix the TV, I had planned to replace IC6001 on the A-Board.
I installed 18 pin sockets in both D-Board locations to make future IC replacements easy. That also eliminates the risk of overheating the ICs during installation. You can find 18 pin sockets for sale online or at local electronics stores such as Fry's Electronics and Radio Shack.
The repair itself was pretty tedious and time-consuming and I wouldn't recommend it to those without some minimal amount of soldering experience. In my case, the hardest part was desoldering and removing the original ICs. I used soldering wick to remove the existing solder.
See the more recent posts in this thread by myself and sholliday<FONT color=#003366> </FONT>for soldering tips and lessons learned.
And there's additional information regarding my repair in this thread:

*** General Caution: Replacing any of the MCZ3001D ICs without any board level diagnostics represents a gamble. Your TV's particular problem could be caused by some other issue. ***

You're welcome and thanks for the positive feedback!
Your post above where you listed the three MCZ3001D locations on the A and D boards was very helpful when I was trying to locate them.

jehill and bobf, you guys rock.
I had to create a profile just to tell you that.
I've got my sony open. Its a kv-32hs500 that died this week.
Well, it started about 2 weeks ago, and I didn't turn it off for 2 weeks. But I lost electricity today, and .... it was over when I got home.
Anyway. I found the D board, and found the circuit locations. For others, if I was above the TV (looking down from heaven I guess), and the screen was at the bottom of my view, and the RF/HDMI inputs were at the top of my view of things..... these circuits would be " right - middle ".
About 3-6 inches from the edge of the board, near a copper wound-y thing.
I'm going to try and tackle the desoldering tomorrow.
GREAT IDEA on the 18 pin socket. That'll keep things simple if it happens again I guess.
Well, this TV is either being fixed by me, or going to the recycle bin. And this forum/posts were the answer.
What did people do before the internet?
PS
You can find the manual (as mentioned) online.
Here are some helpful links at the time of writing.
For those who don't know it, RAR is a program like winzip, but not winzip. Thus you have to get the rar program itself.

Thanks for the positive feedback. I hope that my experience will help others out.
And the internet is an awesome resource. I would not have been able to repair my TV without all the information I found on the internet.

Yes, I did write up some soldering tips but I wanted to clean them up a bit before posting them. I'll see if I can post them in the next day or so..
But, in the meantime, here's an excellent "How-to" link I found:
http://www.pinrepair.com/begin/
This was created to assist pinball machine repairs but the advice applies to any circuit boards. This is very well written and there are numerous illustrations included for clarification.
The information in that link was very helpful to me during my repair effort.

Here are some soldering tips based on my experience replacing two D-Board ICs in my KV-36XBR400.
First a caution:
- Unplug the TV and leave it unplugged for a couple of hours before working on it. Be aware that you can still get shocked after the TV is unplugged because of stored electrical energy. Be careful what you touch. I was never shocked during my repair but I was pretty careful.
And here again is the excellent "how-to" circuit board link that I provided above:
http://www.pinrepair.com/begin/
It's so good it's worth linking twice. :-)
Replacing ICs can be tedious and time consuming. I had some beginner level soldering skills before attemping the repair so I didn't have too much trouble soldering in the new components. What I did find difficult was desoldering the existing ICs to remove them. Desoldering can be a pain.
Before starting, clean the top and bottom of the circuit board with an aerosol spray electronics cleaner. Solder flows much better on clean surfaces. The circuit board on my TV was incredibly dirty from years of use.
Since an IC has a particular orientation on the board, it's a good idea to make a note of this before removing them. You can ruin the IC if you install it backwards. ICs usually have a dot or a notch to identify Pin 1. I also put a dot of "White-Out" on one end of the IC and on the adjacent circuit board. You can also find the "Pin 1" location labeled on the circuit board.
For desoldering I tried two different suction type tools and I found them both to be ineffective. I tried a squeeze bulb and a spring loaded tube. I just couldn't get either of those to work effectively.
What I did have luck with was desoldering braid/wick. That worked great although using it can be time consuming. You can buy desoldering wick online or at electronics stores such as Radio Shack and Fry's Electronics.
Before desoldering, you might want to remove the body of the IC by clipping each of the legs off. This is a suggestion that a local Sony service technician and it's the technique that I used. This allows you to desolder one leg at a time and you don't have to heat multiple legs at the same time to pull the IC. You can also clip all the legs on one side to allow you to bend the body of the IC up to allow easier access to the opposite row.
Leave as much of the legs in place as possible. A taller leg will be easier to grab when you want to pull it out. Use a very small shear cutter tool that you can find in an electroincs store. I bought an $5 Xcelite 170M at my local Fry's Electronics and that worked fine. Here's what one of these shear tools looks like:
http://www.remelectronics.com/ShowcaseDetail.asp?nShowcaseID=15
This tool needs to be small so that you can reach the legs without being blocked by the surrounding components on the board. I actually slid the rubber handles off the tool to allow for even easier access in some of the tighter spots.
After cutting the legs off, I removed as much solder as possible from the bottom of the circuit board. (The IC locations are labeled on both sides of the circuit board.)
After desoldering, I grabbed each leg on the top side with a hemostat and heated the leg from the bottom with the soldering iron. If you have a temperature controlled soldering station, I read in an electronics repair book that a temperature of 665 to 680 degrees F works well for desoldering. That's the temperature range that I used.
Be careful not to pull up any of the surrounding circuit board trace material.
After all of the legs were pulled I used soldering wick to remove any remaining solder in the pin holes. A bright light applied behind the circuit board can help you identify the pin holes where more solder needs to be removed. A darkened room can help here.
I used a head-mounted magnifying visor and that really helped with the fine soldering.
If you remove the board from the TV, take some time and label all of the connectors. That will save you a lot of trouble when you reinstall the board. I used masking tape folded back over itself for this. You may also want to take some digital photos.
Here's a photo that I took of the 18 pin MCZ3001D IC8002 on the D-Board of my KV-36XBR400 before I replaced it. As you can see, accessing the IC is not entirely easy with other nearby components:
As I noted previously, replacing IC8002 did not fix my TV. Replacing the other D-Board MCZ3001D IC, IC6501, did fix the TV. I didn't take photos of that IC but it is even more difficult to access. It's surrounded by a U-shaped aluminum heak sink which made removing the IC more difficult.
Before soldering in the replacement IC, seriously consider installing an 18 pin socket. This has several benefits. First, it eliminates any risk of overheating the IC when soldering it into place. Second, it makes a future replacement of the same IC a snap. Just pop the old one out and plug in a new one. Finally, a socket allows you to test fit the IC before installing the socket. This will allow you to bend the IC legs, if needed, to fit the pin holes without having to deal with the cramped confines of the D-Board. I had to slightly bend outwards the legs of both ICs that I installed. These sockets are less than $1.00 each and you can find them at Radio Shack and other electronics stores.
For the solder itself I bought a roll of very thin, 0.032" diameter, 60/40 rosin-core solder. The thin diameter works well for the fine work required. I also bought a bottle of liquid rosin soldering flux meant for electronics. I found this at Sears (Sears Product Number 9-80063). I applied the flux to clean the pin holes and to help the solder flow.

Did you ever get this resolved?
I have a 36XBR250 and it is totally dead. Seems from all the postings it could be the D-Board. Was wondering how you diagnosed what the final problem was and how you fixed it.
Thanks

Hello everyone! I'm having the same problem as sanbee. LED/Standby continuous blinking red light 5 times. I've been able to power cycle the 36XBR450 successfully twice and just left the unit turned on. A couple of months later the unit just shut off. Now I can't get it back on no matter how many time I power cycle this. From all of the postings there seems to be allot of talk regarding the infamous D-board. Has anyone with this symptom been able to determine if it was a defective D-board or simply a defective CRT?
Thanks again on any input you may have.
Ed.
p.s. Sign me up for the defective D-board list as well. Thanks

Put me on the list of D boards as well. My XBR was about 1 year and 11 months old. Starting losing vertical hold, then finally the set would go out due to high-voltage issues. My service center came out and I was around $700 parts and labor. Luckily, the part was available. Now I'm fighting with Sony as I think spending this much on a "new" "high-end" TV is ridiculous.
If you're someone that's had a D board go bad, could you please contact me via email? I'd like to start compiling a list of people and see what we can do about this.
I Live in Downingtown and was just told today that I need a whole new chasis for about $1,000. Another service man told me I needed a board that will cost about $450. I will be in touch with sony folks tomorrow. My KV-36XBR400 is 2 years 9 months old and while I love the picture I can no longer turn the set on. I get the 5 flashes no picture or sound. When it first started I had to try 10-20 cycles of on off before it would power up. While the Eagles were in the playoffs I never shut the set off. After the miserable loss to the Panthers I shut it off and has not been on since. I also want the e-mail or phone number that was used to get the partsfor free. Please post for all thanks.

Thanks BobF!...
I got the stuff today from Radio Shack.
Before I read your post, I actually saw the desoldering braid/wick and picked one up. So that worked out well.
I actually bought a couple extra 18-pin banks, to practice resoldering those. They were $.59, and a small board was $2. I think $4 is worth a little practice.
I'm off to the races.
The "is labeled on both sides" (IC) was a great tip.
And about how/why to cut away the chip, before the desoldering. Luckily I already have a mini-mini pair of pliers.
I'll try to take some after-shots when I'm done. (If I'm successful).

I have sucessfully swapped out the old IC's , for the new 18 IC sockets. Now I'm just one UPS delivery away from knowing if it will work.
Parts List:
15 Watt RS (Radio Shack) Soldering Iron.
64-2051
~ $8
Desoldering Wick
64-2090
~ $3
Rosin Core Solder, .32 diameter
64-017 E
(The RS guy told me to get this one instead of the one I had, when I saw I was doing Circuit Board Stuff).
I think this was $3 or $4.
18 Pin Low Profile IC Socket
276-1992
<$1
Qty of 2
A couple observation.
15 Watt was PLENTY for this job.
I'd recommend NOT doing it with anything higher.
And be frugal with the amount of time you hold the iron to the board.
Desoldering:
I ended up not doing the snip-snip thing.
With the wick, I was able to complete clear out the old solder, and pull the chip with the first pull.
The second chip I had to re-desolder 2 holes, but got it out.
The mini-pliers did come in handy here.
When I pulled the first one out, I was like 'Hurray, I think this is going to work".
I will strongly suggest the wick for this job, esp if you're only into soldering for rare instances.
You basically put the wick onto the old solder, near the pin. And you heat the wick, while touching the pin.
The solder then runs onto the copper.
You get 5 feet, I think I used 7-8 inches. You have to keep moving the wick as you get solder on it. I usually cut away used wick after I used about 1 inch. The wick gets hot, so be ready.
I inserted the new 18 pin IC slots and soldered them in.
Soldering was easy. I practiced on the extra board I got from RS. I didnt' need the extra IC sockets, I practiced on the old chips.
I actually had the TV on its face and was able to do the job with the board in a vertical position. Again, be frugal with how long you have the iron on the board. Don't overheat the board.
BE PATIENT WITH THE DESOLDER. It took about 30 minutes to desolder both chips. About 12 minutes to solder them back. And I haven't soldered in 5 years.
Here's a tip. If you desolder and the chip doesn't come out, don't over-force it. Put a bright light on one side, and look thru the holes on the other side. (Have the room dimly lit also).
Then you'll see which pins are clearly/cleanly desoldered, and 1 or 2 holes you may have missed.
Wow, I'm in about $16 now, and the chips are probably <$20.
$36 for a repair, that sony wants $500.
I'll report later if it works. But I'm hopeful.
The IC Pin Socket was such a good idea that could have been easily overlooked.
If you're reading all these posts, and try to do this repair, and it works, take a few minutes to register and post a SUCCESS or FAILURE.
Give back to the internet, it treats us well sometimes.

I found an auction for 5 chips for $20 + $8 (s/h).
So I'm in $28 + $16.
$44.
I think its worth a shot to save an expensive TV.
Good luck everyone else trying the repair.
Let us know if it works or doesn't !

Ok guys.
I wanted to see if the A-board IC6001 would be worth it to swap out, since I have everything apart.
I can't find it.
I found an IC903 but that's not the one I think.
That's the only 18 pinner I can find.
It is hidden? Am I eye challenged?
..
The PDF mentions the IC6001, but heck if I can find it.

In the KV-36XBR400, the IC6001 location is at the back of the A-Board on the left side, if you're standing behind the TV. If you were looking down on the board I would guess that it was in something like a 10 O'Clock position.
And thanks for adding all the excellent desoldering tips!
It's great that you were able to pull the ICs without clipping all the legs. That was a big time-saver.
Best of luck when you plug in the ICs!

shollday,
If you haven't already, make note of the proper orientation of the ICs in the sockets since it is possible to install them backwards. I used white-out to mark the ICs and the adjacent section of the circuit board.

Ok, I got the KV-32HS500 manual:
http://www.eserviceinfo.com/downloadsm/25423/Sony_KV-42DRC800,%20KV-32HS500,%20KV-32HV600,%20KV-34DRC500.html
Or
http://www.google.com/search?hl=en&q=KV-32HS500+site%3Aeserviceinfo.com
(you have to download all 7 parts by clicking
0 -- then 1 -- then 2 --etc --then 6
In that manual you can do a search for MCZ3001D and you'll find only 2 references, which are the same 2 "d-board" references above.
So I don't think the KV-32HS500 has the third chip.
..
Also, the bottom of the board has the "1" pin marked, and if you go to BobF's tutorial url link, you'll can determine how to find the 1 pin location on the chip itself. Thanks BobF for that really good tutorial.
..
Ok...I'll post a followup when I get the chips.
Will it be in time for the Superbowl?
Only UPS knows.

Thanks for the pin 1 identifying information. I added that information to my "Soldering Tips" post.
And may the UPS truck arrive before the Super Bowl!

Ding Ding Ding Ding Ding !!!!
Ok. I got the chips in the mail.
10 minutes later I pressed the "ON" button.
And ....:::drum roll::::
Sony is working again!!
Wow, what a great feeling.
I can't tell you how grateful I am for all the help and info.
It kinda makes you mad knowing Sony probably knows its a couple of dumb chips, and won't fix these suckers for <$100. Chips that cost me $6 or so each. Which probably cost them a few dimes.
Oh well.
Superbowl in HDTV, here I come.
Thanks again. If you find the info on this post useful, please post your success story....

Congratulations on the successful repair!
I know exactly how you felt when the TV fired up for the first time.
Hopefully our experiences will help others that might attempt a repair.

Wow, great info in this thread!!
I watched the Superbowl yesterday, 02/04/07, and tried to turn on my Sony KV-36XBR400 this Monday morning and got all the classic symptons described in this thread...no picture, got sound but goes out after a few seconds, then the blinking red LED which currently is blinking 7X...now 4X. I unplugged, got online, and found this wonderful thread. This set is about 5 years old and has performed flawlessly up until now. I shelled out $2500 for this set and stand, and would hate to lose such a fine product over something as negligible as replacing IC's on a PCB.
At first I thought the temperature in my house had something to do with it as we're currently experiencing bitter cold weather and my heating system can't keep up...low 60's in my house. But everything is pointing to this IC6501 (D-Board).
Are there anymore success stories on this procedure? How long do you leave the set unplugged to safely attempt this procedure? What is actually involved in removing the board itself...mounting screws, plug-ins, etc.?
Any help will be greatly appreciated as this semi-retired guy has a limited income.
Thanks in advance,
Joe

Joe,
First let me note that your TV failing right after the Superbowl is direct violation of Murphy's Law. Typically they fail right before the Superbowl. 
Anyway here are some thoughts on your situation with the caution that I am not a service tech.
Your problem may not be IC6501. You really can't diagnose the actual cause with the blink codes. It just points a service technician in a certain direction. So be aware that any repair attempt without some board level testing is a bit of a gamble.
When I repaired my 36XBR400, I basically gambled that one of the three MCZ3001D ICs had failed. First I replaced IC8002 and that had no effect. Then I replaced IC6501 and that fixed the TV. If that had not worked I planned on replacing the third MCZ3001D located on the A-Board (IC6001). But I didn't do any board level diagnostics.
But do a forum only search for "XBR400" and "four blinks" or "four flashes" and see what others have experienced. (I actually didn't get a diagnostic code with my TV since the blink pattern was non-repeating.)
As for other DIY repair success stories, I really haven't seen too many online. Most of the ones I've found are in this thread.
On the shock hazard question, I left my TV unplugged for several hours before working on it but there still may be a chance that you could get shocked. Perhaps one of the repair techs on this forum could comment on that.
As for removing the board itself, it's much like the process involved in removing a motherboard from a PC. But I didn't actually remove the D-Board for my repair. I removed the entire lower chassis which holds the D-Board and the A-Board. I did my soldering on the D-Board while it was still mounted in the chassis. Sony designed this chassis so that it slides right out of the TV. There are many connectors that you'll need to disconnect before doing that.
See my repair report on Page 9 of this thread for more details. I also included a list of other repair options that I considered. And on Page 10 I posted some soldering tips and lessons learned.
Finally, these problems can be sensitive to temperature. I read one report where someone was able to get his XBR400 to turn on by heating the D-Board with a blow dryer. Others have suggested that this could be used a a crude diagnostic tool. I tried this without success on my TV.
Good Luck!
Bob

Thanks for your reply Bob.
I called up the only TV guy here in the village and of course he said it has to be diagnosed. I did ask him if he repairs just PCB's and he said yes. So if I brought him the board and buy the parts, he would do the board repair work for me.
I understand this is all a guessing-game-way of doing things, but there are so many identical situations here that the %'s look good to me. Is there any unsoldering needed to be done to remove this board?
I did try the hair dryer routine but not knowing the exact location of the board...proved to be futile. I will wait for this weather to break and when my house gets back up to normal temperature, I will see if this problem still exists. In the meantime, I still got my trusty old dinosaur...the RCA COLORTRAK 2000 !!
Thanks,
Joe

That's a great idea. I actually tried this, although it didn't work out in my case. I brought my chassis to a local electronics technician and he agreed to remove and replace all three ICs for $45. I thought that was reasonable and I asked him to go ahead.
Unfortunately, he spent about 45 minutes attempting to remove the first IC in the IC8002 location without any luck. He was using soldering wick and he was unable to get enough solder out to free the IC. He finally gave up and apologized for his inability to complete the job.
But I'm guessing that nearly any experienced technician could tackle this job.
Be sure to get an agreement on the labor cost before you commit to the service. And seriously consider the installation of 18 pin sockets. That will make future IC replacements a snap as no soldering would be required.
Here's the thread where I posted that update:
http://agoraquest.com/viewtopic.php?topic=26401&forum=34&start=0&select_page_number=1
It has more details on my repair process and it also details another forum member's IC replacement that, unfortunately, did not work out.
You could also send your D-Board off to a place like tristatemodule.com and they'll repair your board for $150 plus shipping:
http://tristatemodule.com/
I probably would have sent my D-Board there if my own repair attempt failed.
There's no soldering involved in removing the D-Board. I did have trouble disconnecting the two red wires that connect to the flyback unit on the D-Board. I just could not get either of these wires to release. I ended up cutting one of them so I had to splice it back together later. The second red wire ran up to the "anode cap" on the top of the CRT and I just disconnected it at that end.
Be sure to label all the connections. And you might even want to take some photos.

Well Bob, I have had my Sony off (still plugged in however) since my last post here and been using my old trusty RCA Colortrak 2000. I tried turning the Sony on today and WAHLA it came on 1st attempt!! It's not a fix but all my other equipment is hooked thru it, so I'll just leave it on until the weather breaks here. The reason I say that is, my house was a little warmer today with a heat wave in the 20's outside! So I now suspect that temperature is indeed an issue here. I'll keep you posted on further developments.

Joe,
Thanks for the update.
If your TV behaves like mine did, at some point it will stop working altogether, regardless of the ambient temperature. But who knows?
Good luck with it!

I have a 36XBR400 and had the 4-7 blinks issue, did the unplug while its on wait 30 secs and turn it on and it worke the TV ws on for a few days till I turned it off.
Well I followed the instructions bought, the ICs and sockets and replaced them, but now the tv does not have the same blinks, it seems to blink more lke 7-10 times and then the light stays on, no picture no sound. At first it made the same sounds like it woas about to power up, but after messing with it it just clicks like once, no more acting like it is going to come on.
Any ideas what I did wrong? I did all 3 ICs.
Thanks

There is the very real possibility that none of the three MCZ3001D ICs were causing your problem.
Without any board level diagnostics, replacing those ICs is a gamble.
Power up problems can be caused my other problems.
Did you ever get a copy of the common D-board failures from forum member jehill?
See this thread:
http://agoraquest.com/viewtopic.php?topic=26985&forum=34&keyword2=electronics
Be sure to send him the request via a private message. Don't request a copy in that thread. The service bulletin covers several Sony models including the 36XBR400.
Regarding the initial "4-7 blinks issue", did you get a repeating or non-repeating blink pattern? In other words, did it blink a certain number of times, pause, and then repeat the sequence again? If the blink sequence does not repeat it does not represent a diagnostic code.
And did the number of blinks vary between 4 and 7 blinks randomly or did it change over time?
Exactly how many times is it blinking now and is that a repeating or non-repeating sequence?
Did you disconnect any connectors during the repair? If so, you might want to double-check all of those.
And did the desoldering and soldering go smoothly? Another possibility is that something was damaged during the repair.
Finally, regarding the following comment:
At first it made the same sounds like it woas about to power up, but after messing with it it just clicks like once, no more acting like it is going to come on.
You might have heard the deguassing feature and that it is not always triggered when you turn the TV on. So not hearing that sound is not an indication, by itself, that something is wrong.
Good luck!
Bob

Well initailly it seems to have the same symptoms as everyone else. It would blink 4-7 times then the light woudl go off. It now seems to blink several times, and then the light stays on. No repeating, then or now.
We did of course take the boards out so we unhooked everything, but rehooked it, we also had a couple of holes that the traces were bad, but we tapped wires on to ensure they had a connection.
Not sure what to do from here, guess we bricked it even worse.

One forum member actually replaced the ICs without removing the D-Board from the TV. He just rotated the chassis up into the "service position".
I couldn't quite manage that so I removed the entire chassis from the TV. But I did leave the D-Board mounted in the chassis.
Well since the blink codes are of the non-repeating type, they're apparently not diagnostic codes. See recent posts by forum member BUDMAN for more information on this.
But count the number of flashes and post that result here. Perhaps one of the other forum members could still make something of that.
Are you positive that the ICs are completely inserted into the sockets you installed?
And you might want to touch up all of your new solder connections to make sure that they're all good.
For other options, such as sending the D-Board off for repair, look for my repair report on Page 9 of this thread:
http://agoraquest.com/viewtopic.php?topic=1121&forum=34&start=80&select_page_number=9
Good luck!

Yeah the guy I had help me do the solder de-solder is pretty adept there is one plug on the C or D board that did not have a wire going to it, but there were not any plugs so we assumed it was empty before.
Oh well, guess another TV to the landfill.

I just joined this group and find it great. I also am experiencing problems with my 36XBR400. Build date Dec 2000. It started having problem turning on and now will not turn on. Flashes 4 blinks. I suspect the IC. I will order those and tell you how it goes. I repair video games and pinball machines so it will be a snap for me. ALWAYS socket your IC's. That makes for easier repairs later.

Thanks for the update.
I'm sorry it didn't work out for you. Well at least you gave it a shot.
You might want to offer the TV on something like craigslist.org. Perhaps someone else could use the parts.

Best of luck with your repair attempt!
Your pinball and videogame repair experience will definitely be useful. One of the best "how to solder" links I found was on a pinball repair website. I posted the link to that site on Page 9 of this thread.
As a general caution, your TV's problem may not be due to a faulty MZC3001D IC. Some people have had luck replacing these while others have not.
Be sure to request a copy of the Sony Service Bulletin that forum member jehill offers in this thread:
http://agoraquest.com/viewtopic.php?topic=26985&forum=34&keyword2=electronics
It provides a list of the most common D-Board circuit failures.

Just found this forum...
This is the first time I've done any real research on the XBR400 since I bought it way back in 2001. I was shocked when I read about all the defective tvs. I have never once had any issues in my 6 years of ownership. This was my main TV and I used it everyday until recently purchasing a 46" XBR2. The worse problem I've had with the XBR400 is having to move it in and out of several residenses over the years. This TV is a beast!
Anyways...I was just looking to see what some of you had as far as settings. I never messed with any of the picture settings over the past 6 years that I can remember and was just now thinking they could use some tweaking since I have hooked up the PS3 and the picture can be very dark at times while playing Resistance. Anyone care to share their settings? Or better yet, maybe refer me to a thread with users specific settings for this TV.

I ran into the no picture but sound issue about a month ago with the 36xbr400. We purchased the tv back in 2000. After looking over this thread my wife and I decided it was a good opportunity to upgrade to flat panel hdtv. So we purchased a new 50" Plasma...but instead of chucking the XBR I would like to take a shot at fixing the tv myself. My brother has experience sodering electronics. I have no experience in this territory which leads me to a few questions. The MCZ3001D is the chip that I need and I may need three of them. They are located in:
IC8002 (D-Board)
IC6501 (D-Board)
IC6001 (A-Board
Correct?
When I see these things on ebay (mcz3001d) and they say 5 pc or 4pc that means they'll send 4 or 5 chips?...the
ebay listings are not very clear
Will I need a schematic of the layout or will I be able to find the boards when I remove the chassis?
Thanks for all the help.

Frank,
Yes, those are the three locations for the MCZ3001 ICs.
For the eBay listings, it's best to confirm the number of ICs with the seller.
You will be able to find all three ICs just by looking at the A and D Boards. They are labeled on both sides of the printed circuit boards.
See Page 10 of this thread for some soldering tips that I posted:
http://agoraquest.com/viewtopic.php?topic=1121&forum=34&start=90&select_page_number=10
I strongly recommend the use of 18 pin sockets.
Be aware that there's no guarantee that your TV's problem is related to any of those three ICs.
Good Luck!

Bob- Thanks for the reply. I know it's a bit of a shot in the dark but figured it was worth it as it will just replace a garbage tv in the kids playroom if it works out...

I totally understand.
I'm sure a lot of these TVs are ending up in dumps even though a $6 IC might have been all that was needed for a repair. It's a real shame.
When it's working, the 36XBR400 is a wonderful TV.
I've had mine hooked up to high definition cable for about a year now and I still find myself commenting on the incredible picture.
Best of luck with the repair attempt!

I don't have a basement, but I do have a large room upstairs that could be used if it were not for the fact that it is presently used for storage of my sons' stuff. That should change when they move into their own homes.

I have been using my KV36XBR450 to watch HD ever since I bought it in October of 2002. It still works like a champ, but its only equivalent to a 33" HD set. Although I probably could repair the set, thanks to the knowledge accumulated here on Agoraquest, I probably will use failure as an excuse to get a new big screen set. Currently, I am drooling over the KDL52XBR3, although I would prefer a 60" set. The only way for me to watch a sporting event and take advantage of the HD is to sit so that my head is bout 5' from the set. This really annoys my wife. A 60" set would be perfect!

That's what we did...it was kind of an opportunity to upgrade to a plasma...but for sporting events and movies I have a front projector in the basement. If you have the space, a high def front projector can't be beat. Yeah, my 50 inch plasma is nice but I have a 10 ft flat screen in the basement- just can't get the friends to go home.

Hi Bob,
Well, you were right...after leaving my Sony 36xbr400 on constantly since Feb. when I posted here, I had a power outage while at work and she won't come on at all now.
I was surprised that my power bill hardly varied at all during this time...anyways, I'm going to attempt PCB removal tomorrow and have the local TV guy replace the IC chips. If you have any new news on this problem, a prompt reply from you would be greatly appreciated.
Thanks,
Joe

Joe,
I'm sorry to read that your 36XBR400 no longer powers up. I can relate to the feeling.
I have a couple of suggestions/comments.
If you do remove your D-Board, or the entire chassis, take some time and label all the connectors. That will make the reinstallation much easier. You might also want to take some photos.
You may have trouble disconnecting the two red wires that come off the flyback unit on the D-Board. So be prepared for that. I was unable to disconnect either of those two wires. For the thicker red wire, I just disconnected it at the other end where it hooks up to the top of the picture tube( Anode Cap). And I ended up cutting the other red wire that runs up to the C-Board at the back of the picture tube.
Be sure to agree on a repair cost before the repair is started.
I took the chassis from my 36XBR400 to a local repair technician but he gave up after having trouble desoldering the ICs.
Consider having 18 pin sockets installed for the ICs. The sockets are inexpensive and they will allow easy IC replacements in the event of a future failure. That's what I did for both the IC8002 and IC6501 locations on the D-Board.
Forum member maethros posted some information that the MCZ3001D IC had been replaced with a new, potentially upgraded, IC.
Here's a link to that thread:
http://agoraquest.com/viewtopic.php?topic=28339&forum=34
I haven't seen any more information regarding this but you might want to look into it in the event there might be a better or more reliable replacement IC.
Finally, understand that any repair without board level diagnostics is a bit of a gamble.
Good Luck!
Bob

Hi Bob,
Well I finally got around to pulling the whole chassis out tonight. I don't watch much TV in the summer but my old RCA Colortrak went out too, LOL. So I have no TV at all now.
Like you say, there are alot of connections to remember but I took your advice and labelled everything. And I too, had to cut that one red wire going to the board behind the tube. I found all three IC's that are mentioned here and ordered that 5 pack on Ebay and will buy some sockets locally here.
Pretty messy job too and me being a smoker, made it even worse, YUCK!!! I'll have the local repair guy change out the IC's. They all look accessible except for that IC6501 that is surrounded by a U-shaped heat sink. How in the world did you change out that puppy??? I looked at that and said NO WAY JOSE, LOL. But I'll give ya credit Bob, you must have the patience of Job  .
I'll keep ya up to date.
Later...Joe

Joe,
Thanks for the update!
I had the exact same reaction when I first saw the IC locations. IC6501 was a particular concern because of that U-shaped heatsink. I said to myself there's no way I can replace that IC.
So I made the same decision that you did, I brought the entire chassis to a local repair technician. He agreed to replace all three ICs for a very reasonable cost. But after struggling with the desoldering one IC for something like 40 minutes he threw up his hands and gave up. He didn't charge me for anything and he was very apologetic.
It was at that point that I figured that I had nothing to lose by making my own repair attempt.
Accessing IC6501 was not as bad as it looks. I did all of the heating from the bottom of the board. And a head-mounted magnifying visor was a big help.
But it was a very tedious job as I had to keep flipping the board around 180 degrees as I pulled each IC leg out.
Good Luck!
Bob

Bob,
Well, I just got my chassis back from the TV repair man in the village and he did a great job. Installed the sockets and IC's and very professional looking I might add. He gave me a price quote and stuck by it, after having trouble (over 3 hours labor he said) because the old IC's were soldered on both sides of the PCB's.
All costs:
1. package of 5 IC's (MCZ3001D) on Ebay............$28
2. 3 18-pin sockets from Radio Shack...................$2
3. labor charge for install of IC's and sockets.........$54
Total cost of this project......................................$84
I took pictures of the whole chassis removed and all the IC's involved but this forum won't allow me to post them...probably because I use the MSN browser.
Anyway, I installed the chassis yesterday and guess what???...........................................................
........................................................................
........................................................................
....My Sony IS BACK UP AND RUNNING!!!!!!!!!!!!!!!!

I was so excited, I watched TV all night...I missed it so much...LOL. It's not as sharp as it used to be, but still better than most. I think I may have changed a setting when I was removing the chassis. Where those 2 big red wires go to, there is some kind of adjustment screw, possibly a potentiometer. I messed with that screw figuring it was holding those 2 wires somehow....NOT!! If anyone knows anything about this screw, give me a holler.
I want to thank BobF in particular and everyone else who had a hand in contributing to this thread. I would never have attempted this project or be able to afford it for that matter, without all your help. THANK YOU ALL!!!!!!!!

I just got a complete chassis from Ebay for .99 cents that the guy said it had 5 blinks.I put it mine and it turned on and has had no problems,so maybe he had a bad tube?.But anyways after about 6 months of it sitting it's now alive again.

Well, I just got my chassis back from the TV repair man in the village and he did a great job. Installed the sockets and IC's and very professional looking I might add. He gave me a price quote and stuck by it, after having trouble (over 3 hours labor he said) because the old IC's were soldered on both sides of the PCB's.
All costs:
1. package of 5 IC's (MCZ3001D) on Ebay............$28
2. 3 18-pin sockets from Radio Shack...................$2
3. labor charge for install of IC's and sockets.........$54
Total cost of this project......................................$84
I took pictures of the whole chassis removed and all the IC's involved but this forum won't allow me to post them...probably because I use the MSN browser.
Anyway, I installed the chassis yesterday and guess what???...........................................................

I hope that's my issue. I'm going to try it and find out since it seems everyone who leaves their TV on for a few months because it only turns on once in a while does this and it works.
If not, I've still got a broken TV

It was the only way I could afford a fix for my TV Chris, being semi-retired and on a limited income.
When removing the chassis, be sure to label all your plug in connections you remove, as there are a bunch to remember...there was one red jacketed wire I had to cut because I found no way to disconnect it manually. The TV repairman said this was the focus wire...I spliced it back with an inline connector. My picture is not as sharp as it used to be, but still better than most.
I took pictures that I can email you as this forum will not allow me to post here for some reason...incompatible browser, probably.
Good luck with your repair Chris and feel free to ask questions. BobF did this whole project himself and was most informative with his detailed posts in guiding me through all of this.

As much as I'd love to pay someone else to do soldering for me...I just can't justify it. I've changed out the 2mm LED's in my car so I'm pretty confident in my ability to do it. Started removing connections last night and labeling them with a crayon
That and I just totally took off the speakers...I figured since I don't ever use them, why have them

That's great Chris!! I neither had the tools nor the experience for working with such small components. You'll save even more!!
Even my TV guy had trouble with these IC's because they were soldered on both sides...so you'll probably have to remove the boards from the chassis too. Good luck!

Yes, the service technician that I brought my chassis to also noted that the ICs were soldered on both sides of the boards. He told me that made the desoldering task especially difficult. (He told me that as he gave up on the job.)
And you can replace all three ICs without removing the D-Board from the chassis. That's how I replaced both the IC8002 and IC6501 ICs in my TV.
Some of the plastic structural braces do make things tight in spots but it's not too much of a problem. And the chassis itself also can serve to hold the D-Board in a vertical position for soldering.

Well it looks like I will be putting sockets in mine also as it started having issue now.
It turns on if it sits for a while.But when I try it right after I turn it off it blinks like normal then stops blinking and does nothing for 10-15 seconds then just goes back into standby with no blinks.With the other A board it blinks 7 times.

Well it's alive again.I removed just IC6501 which was alot easier to remove after removing the large heatsink thats in the way and a few caps.But I did put a socket in there just in case and used the IC thats by the FBT from my old junk D board and it powered right up.
I wouldn't waste the time on the other two IC just replace IC6501 as they are a PITA to remove and it seems like thats the one that goes bad.

Congratulations on the successful repair! Good job!
How difficult was it to remove the heatsink? I thought about removing that on my set but I ended up swapping the IC with the heatsink in place.
And I actually read several online repair stories where IC8002 was the problem IC. That's one reason why I changed that one first.

Removing the heatsink was pretty easy using a RadioShack desoldering iron and the screw is easy to get to also.
The problem started after I adjusted the VCEN and VPIN to 0 trying to get rid to the bow on the bottom.Guess I'm going to deal with the bow,plus when they were at 0 the tube was louder when it powered up.

Thanks for the info!
Did the bow in your picture appear after you installed the new IC? Or was that a pre-existing condition?
And can you provide more details on how the tube was louder?

No it was always bowed,but with the new IC the Convergence was off.
When the tube got power from the FBT it was louder like there was more of a jolt which probably killed the chip.

Thank you for the details. The focus on my 36XBR400 seems fine but that's good to know in case it needs an adjustment down the line.

Here's an update that might help some of you guys.
Remember I said my picture wasn't as sharp as it was after my repair? Well my hunch was right about that phillips adjustment screw that is located where those 2 big red wires go in. IT ADJUSTS THE FOCUS...and now it's just as good as it always was!!
This all started when I broke down and decided to get into the high def rage going on right now. I bought an Onkyo TX-SR605 receiver and a Toshiba HD-A2 HD DVD player...all state of the art stuff for high def audio and video. The Sony XBR400 is not a 1080p TV, but will accept 1080i via the component hookups as it doesn't have any HDMI hookups. So I got component cables running from the HD DVD player to the Sony and an HDMI cable running from the HD DVD player to my new Onkyo which allows for the latest digital sound.
I'll tell you what, this old dinosaur Sony still cranks out a picture that I dare you to compare it with ANYTHING out there!! I know the flat panels are the rage now, but this old CRT tube beats 'em all. Eventually I'll break down and buy a 1080p TV...but for right now I can't tell the difference with these old eyes

Thanks for the helpful information. Can you provide additional details on how you made the adjustment? Did you use a mirror to see the screen as you adjusted the focus? Did you use a calibration DVD, like Avia, to display a test pattern?

I just wanted to thank everyone here
I ran across this forum site when looking for a fix for my Sony kv-34xbr800.
The info I read here really helped me fix mine
I was having that fault with the 7 blinks of the stand-by.
I read that it was either IC8002 or IC6501 (MCZ3001D, replaced by the MCZ3001DB chip). I replaced IC6501 1st, didn't fix. then replaced IC8002, FIXED IT . I even took the one from 6501 and put it in the 8002 slot (I did buy 2 new MCZ3001DB chips. which I did use one in the 6501 slot). I even installed sockets for easy replacement down the road, and have a spare for now
As I have owned mine since 2002 and it just started acting stupid when I moved it (for the 5th time of moving, sucks moving it, but I love the TVs PQ and I believe CRTs are a better TV. IMO). It at 1st would not come on the first time but hitting the power again would get it to come on. That lasted 2 weeks then it wouldn't come on (atleast not at first or not until I unplugged it for a day). But that only worked a couple times
Finally found you guys and did what it took....
Now it is working again (like before this) and I am so glade
Thanks again
good luck everyone with XBRs

You are welcome Bob
I do have a question for everyone here....
I have read in other forums that I cannot connect a computer to the DVI input of this TV (kv-34xbr800). I have the ATI 7500 all-in-one video card with DVI out. I connected it to the DVI of the TV and it seems to be working fine.
My question is....Will it hurt the TV? or the DVI input?
In the TV manual it says it isn't made for PC. But I like the picture quality from the PC. I do notice a little flickering when watching a movie (certain colors, in certain scenes, in the background flicker). It may be the dvd or video card can't handle the high resolution?
Does anyone have any insight on this subject???
Thanks ahead of time

It,s ok the dvi video card is same as a video or dvd or a tuner but it will not be as good pic, the best pic is if you had a tv with computer input ready.

OK thank you RA!!
Thats kinda what I thought. But it is a pretty damn good pic, as long as I turn the resolution all the way up on the video card (1792 by 1344, I think thats max? I thought before I saw 1900 by xxxx). I know it isn't full HD quality, but understand my TV isn't 1080p, max is 1080i.

I have a 36" XBR400 with the "shuts it self off" problem so many others have in this forum. I used all the good info here to order replacement MCZ3001D parts and tried replacing them but still am not up and running.
The symptoms: My XBR400 turns on, but within about 1 hr or less shuts itself off. It has the 6-blink flash code. Sometimes it shuts itself off in as little as 10 seconds, but it varies quite a bit.
Step 1: replaced IC6501 (D board) based on others having success with that. After completing the job, it still shut off after about 40 minutes with the 6 blink code.
Step 2: replaced IC8002 (D board). After completing this, it still was shutting off after about 40 minutes.
The good news was at this point I was no worse off. The TV would still stay on for about 40 minutes. I was glad I hadn't made things worse.
Step 3: replaced IC6001 on the A board. After this, I tried to turn the TV on and it shut off almost immediately with now a 7-blink pattern. Now I'm worse off than before. I'm going to try and see if I screwed something up in this last step to at least get back to my 6 flash pattern.
I've searched many of the topics in this forum and seen others with the 6 blink pattern, I haven't found anyone with a 6-blink pattern that solved the problem.
Thanks to those who took the time to post their success stories (BobF) with other blink-patterns and special thanks to jehill for the Sony D-board common failure notice.
Does anyone know of anyone that self-repaired an XBR400 with the 6-blink pattern?

Just to be clear, do you have a repeating 6-blink pattern? In other words, does the standby light blink 6 times, pause and blink 6 times again? If the blink sequence does not repeat, it's not a diagnostic code. (FWIW, my KV-36XBR400 did not produce a repeating blink code. Over time, my TV produced 5, 6 and 7 non-repeating blink sequences.)
Assuming you removed the D-Board or the lower chassis, you might want to disconnect and reconnect all of the connectors. Perhaps one of the connectors is not fully seated.
Did you use 18-pin sockets for your new MCZ3001D ICs? And do you have any spare ICs? If so, you might want to replace each of the installed ICs in the event you have a bad IC. That's probably unlikely, but it's an easy thing to check if you used sockets and if you have some spare ICs.
Did you check that all of the the ICs are installed in the right direction?
Finally, I haven't seen too many reports of these TVs turning off. Most of the reports are for a TV that won't turn on in the first place.
Good luck!
Bob

Hi Bob,
Thanks for your quick reply. I've provided some answers below:
Yes, it was a repeating 6 blink pattern with a pause between each (until that last IC6001 repair screwed things up).
I am going to re-check all connectors, and all solder connections, and especially check that IC6001 is seated correctly. I have some spare MCZ3001D's and will try that too. I did use sockets so it won't be hard now to swap out the '3001D's. All IC's are installed in the right direction. FYI - I did disconnect the entire chassis and worked on the D and A board while installed on the chassis, but outside the TV on a static-grounded workstation. With difficulty I was able to get the smaller red wire to come out of the flyback transformer.
Even if I manage to un-do whatever problem I created in step 3 (IC6001 above) I'll probably still be back to the 6 blink code. There are some other D-board common failures in jehill's bulletin and I might try to source those parts and try them, BUT based on the 6-blink pattern this might be an A-board problem (see blink-code summary topic) and I don't have a bulletin for top failures on it.
Any pointers on the 6-blink code and potential fixes are greatly appreciated.

You also could check,C6508(47uf/25v),C6532 (.056/800 change even if checks good,also check IC 6011 5v reg under large sink, also you have to look at ic9001,ic9002, ic9003,d9017,q9012,q9008,IC5003=12vreg,IC5008=5/9vreg,also r8053,r8054,r8055,SMDvoltage Sense Resistors from 200v line to HV OSC IC,and check the little blue cap next to the horizontal output transistor .oo47 2 kv,.If i were you would get this 10bucks service manual.and good luck, http://www.justmanuals.com/sony-trinitron-color-kv32xbr400-36xbr400-38drc1-38drc1c-chassis-dx1a-parts-service-p-2475.html

Hi Ra,
Thanks for the info. There's a common D-board failure Sony service bulletin, which narrows the devices to check on that board. Does anyone know of an A-board common failure Sony service bulletin?
Also, I already have the Sony DX-1A Chassis Circuit Description and Troubleshooting manual which I think is what you gave a link to above. I was able to download for free using a different link somewhere in Agoraquest, but I can't remember which topic is was under.

Thanks jehill. Well I managed to fix whatever I did wrong changing the third MCZ3001D and at least I'm back to where I started. TV comes on and works fine for 5 to 45 minutes but then shuts off with a repeating 6 blink pattern.
I tried the diagnostic on-screen setting (pressing display, 5, volume down, and then power button on the remote) and it shows zero's for faults except under 6 which says "Low B" with a count indicating how many times it's happened (like this "6: Low B 1").
If anyone has an idea of the root cause for this I would greatly appreciate.
Also - be very careful with removing that red wire from the flyback transformer, it does come out but can break off in the process leaving a piece of wire inside that prevents re-installation. It's better to go with BobF's method and cut-and-splice (or better install a connector) it back together. I can't believe Sony would install connectors for everything else on the DX-1A Chassis but not this!

That was exactly the concern I had when I tried to pull out the thinner red wire from the flyback. I thought it might break off inside the flyback and complicate or prevent reinstallation. So it looks like pulling on the wire to remove it can be a hit or miss proposition.
How did you go about reinstalling the wire?
On you TV's problems, I'm wondering if you have a component that's failing when it gets too hot. You might be able to run a crude diagnostic by blowing on the circuit boards with a fan. If the TV stays on with the fan then you probably have some sort of overheating issue.
Also, the 6 blink pattern and the "Low B" message is consistent with the blink code descriptions listed in the following thread:
http://agoraquest.com/viewtopic.php?topic=26401&forum=34
In particular:
6 LED Flashes (LOW B OCP/OVP (overcurrent/overvoltage))
• +5 line is overloaded.(A, B Boards)
• +5 line is shorted.(A, B Boards)
• IC6007 is faulty. (A Board)
- No picture
And here's another thread discussing a 6 Blink problem:
http://search.agoraquest.com/viewtopic.php?topic=26401&forum=34&keyword2=electronics
Unfortunately, that forum member, ihatetomatoes, was unable to resolve the problem. But his well documented repair attempts might give you some ideas. He actually helped me out quite a bit on my repair.
Good luck!
Bob

Hi Bob,
Re: re-installing the small red wire to the FBT, I trimmed the damaged end and with some force managed to dislodge the small piece inside the FBT and get the wire reseated. At least I hope it's a good connection, as there's no way to really confirm a good connection other than a hard tug (which I'm not keen on doing).
I'm still hopeful someone will see these posts and have a successful self-repair story for the 6-blink auto-shutoff after ~30 min problem.

Does anyone know the Sony part number (the one for searching for parts on the Sony parts website) for the flyback transformer used in the 36XBR400? I see a part number in the below link, but that's not for a 36XBR400.
The number on the top of my FBT is >PPE+PS-FR40<.

If another forum member is unable to help, you might want to call or email the Sony parts center:
http://servicesales.sel.sony.com/ecom/accessories/web/contact_us.jsp
The number is toll free within the US. Perhaps there's also a toll free number for Canada.

I just looked in the service manual and confirmed that the part number for the FBT is 1-453-346-11. You may order it for $141.77 at http://servicesales.sel.sony.com/ecom/accessories/web/productSearch.do. Use the Part or Accessory Number search to locate the part.

I have a KV-32XBR400 and have given up trying to fix it. I believe I have a D-board failure though could be something else?
If anyone wants parts or even the complete TV, pay for shipping and I'll send them off. I live in the Montreal area for any local pick-up.

I just received a used KV-36xbr400 that worked but by the time I got it muscled into the house it just sat there blinking 7 times continuously. After letting it sit for 2 weeks my wife said either fix it or get rid of it. I was writing an ad on freecycle when I decided to do a search on the problem and ended up on this great site. After reading dozens pages I went and turned the TV on again and presto on it came. I know from reading all the posts that this is probably a temporary victory and as soon as it quits again I'll probably try the IC fix since I belive that there isn't anything I can't fix, (with the right guidance and a bit of luck). Anyway I was checking the various links mentioned and came across this D board at http://www.tristatemodule.com/html/web_specials.html . Does anyone know if this is the part # for the XBR400? I'll probably give them a call and find out. It seems like this is a cost effective solution to the problem of soldering in the new IC's, plus having all the other new caps and resistors seems like a bonus.

I believe the part number for the KV-36XBR400 D-Board is A-1346-948-A. That's what I have in my notes. Here's the link for Sony's part sales group if you want to double-check that:
http://servicesales.sel.sony.com/ecom/accessories/web/index.jsp
If you can find one for a reasonable cost, replacing the D-Board is a great option.

Hi Jehill - you helped me out before with a Sony part number for the FBT. Can you please check your manual once again for the Sony part number for the capacitor at location C6532? This is from page one of the bulletin E28041743 top D-Board failures.
Thanks

I ordered a replacement for C6532 from the Canadian distributor for Sony parts "Able Electronics Inc". It is Sony part number 1-165-954-11. They claim Sony replaced 1-135-998-21 with this part. I hope it works.
- Does anyone know if there a polarity, or "pin 1" on this 2-lead capacitor?
The package says capacitor, Metal PP FILM, 56000P
- Does anyone know if this means the same as 56000pF?

Having issues with a KV-32XBR400 here. I had a repair technician come out, he said it was the Horizontal Output Transistor, but that it could likely be traced back to a bad Flyback Transformer. He told me he could not get the parts, and that I was out of luck. In general, however, he was less than helpful and didn't seem very helpful. I have been scouring the Internets for answers, and I have happened upon this forum. Tri-State Module looks like a good option, and I'm certainly willing to do the work myself. The only problem is, I can't find a technical reference anywhere that would have the part numbers I need. What is the part number for the d-board on a kv32xbr400? Is there anywhere on the board I can find it?

Tri-State Module doesn't seem to have any of that particular D-board in stock. Is there a parts list for the KV32XBR400 on-line? Any recommendations on where to buy parts? Or should I just give up and get a 37" HD Westinghouse or LG Flat Panel for less than $800? I really liked this television, the picture is really hard to beat.

Hello and thanks for the great help from this site. All the info on the KV-32HS500 7 blink trouble that BobF and Jehill provided got my 5 year old KV-32HS500 sony back up. I as many had the tv that just would not turn on trouble and after 3weeks left on we shut her down and she finally said enough. 3 - 4 phone calls to set up a repair told me that was not an option after a rough quote of $450 and another rough quote of $500. One google brought me here and after about two or three hours of reading I was off and running. Now I don't have a huge background in soldering or electronics repair, but have soldered on wiring harnesses and changed a few belts on my 25 year old RCA vcr that still plays like a champ. It hurt to much to send another tv to the landfill espeicially since it was only 5 years old and cost me $1900 bills. Well I was able to put her face down like SHOLLIDAY and put the 18 pin IC sockets in like BOBF suggested. Desoldering was real easy with the wick material if I folded it over once on itself them slid it over the pin from the bottom side then applied heat. The real fun was getting the two new MCZ3001D IC's in place without bending any pins. After some major help from my wife and a little fianese we got them in and hit the power button. No luck just another quick attempt to turn on and the pop and back off. We did not give up and checked all are pin solders real close and noticed two that looked like they may not be making contact with the board. We resoldered those put her upright again and BAM
we had TV again in our living room. After doing a diag in remote commander there are no more errors and we put her back in out entertainment center. We hope to get a few more years of box love entertainment and know just what to do if we have another problem.
Thanks again to all that contribute to this forum and those that post there results after making an attempt at there DIY repair. One tip I would give anyone is research real well on here. The info is here it just takes a little effort to find it.
Thanks again,
Tim in Orlando

Tim,
Congratulations on the successful repair! Another 36" Sony CRT saved from a landfill!
And, as jehill wrote, you're more than welcome for the help. I'm always happy to read that my posted comments and those of others have been helpful. It makes all the typing seem worthwhile.
Thanks for mentioning the need to bend the IC pins. I had forgotten that I needed to bend the pins on both of the ICs that I installed. But I test fit both ICs in the sockets before I installed the sockets. I now realize that I can add that suggestion to my "soldering tips" post. I'll update that when I get a chance.
Thanks for taking the time to post the news of your successful repair!
Bob

Thanks to everyone for the help from this site. I had a Sony KV-36hs500 with the same blinking LED problem that suddenly refused to turn on. Following the suggestions listed on this board, I replaced the two MCZ3001D chips found on the D-board. The whole repair took about an hour or two. Cutting the plastic support on the bottom with a drummel tool as one of the other posters recommended was a great idea by the way!
Anyway after putting everything back together, the TV powered right up.
Two chips cost less than 20$ from E-bay. It sure beats the cost of a new TV.
Thanks again to everyone who posted all the useful information.

I could use the tech bulletin on the KV40XBR800 d board. I have the service manual.
I have located the chips to replace, but anyone have input on how to remove the d board? I am most concerned with the wire type connectors between the A and D boards and the wire from the FBT to the focus board (I think) on the back of the tube. The rest look like pretty easy connectors.

Great help Bob,
I was able to remove the wires, remove the board and desolder the IC's. I soldered in new sockets and am awaiting the chips in the mail. Sure hope everything goes together well and works.
Scott
Thanks to everyone who helped...I could never have made it this far without it.

Chips arrived, I plugged them in and she comes on and shows a good picture. Only problem is a green lower left tinge. Great to have a TV again. Thanks to everyone on the site. I could never have done it without you.

I was just reading another topic but I could not reply there, looks like this is same issue.
I just wish someone could take pictures of all the places we need towork on, or just record a video which would be even better. I am anewbie with these TV type electronics, have been working with computersfor a long time, but TV is whole different planet for me, sincecomputers are pretty straight forward. After being shocked in thefinger about 20 years ago when I opened up my TV's back to hook up someexternal speakers, I never touched another TV. I never solderedanything after burning my finger by grabbing a soldering iron directlyabout the same time (when I was a kid).
I have this hot ice/cold soldering machine, which cools down immediately, I wonder if that will work for desoldering the chips?

If you don't have a deesoldering tool, you can us the braid of a shielded cable to wick up solder. Its not the simplest method, but it works.

If you're referring to one of those ColdHeat soldering tools, don't bother. Those are basically junk and they would be useless for the desoldering task. Search the internet and you'll find many disappointed buyers of those tools. I wish I had done that before buying one. I have to admit that they look nice and they are backed by an excellent marketing campaign.
For this job, just buy a decent soldering iron. I bought a nice Hakko temperature controlled soldering station but many have had great luck with the most basic models.

Thank you BobF. Well, I bought it at home depot for $15, it came with a few stuff on the side, I thought it should be good enough to solder broken chain, or small cables.
jehill, no I don't have a desoldering tool, but if the instructions look simple enough (for me to do this project), I may have to invest in a good desoldering tool, and a good soldering iron.

You're welcome. I bought my ColdHeat tool at Costco and really should have just returned it. But it was a couple of months before I tried to use it on anything and I had tossed all the packaging materials. I'll probably donate it to my local Goodwill and let someone else see if they can get it to work.
On the desoldering task, I would just go with the soldering wick. That worked great on removing the MCZ3001D ICs from my TV.
And, for what it's worth, I had no luck using two different suction based desoldering tools. I tried one of the Radio Shack spring loaded tools and one of the squeeze bulbs. I just couldn't get either of those to work on the IC removal task. To my local Radio Shack's credit, they took both of those items back without a problem.

My wife is saying that there is no way I am going to open up the tv, pull some chips and blow up the house...
I have to wait until I get 100 messages before I can PM jehill and show my wife how easy it is (if it in fact is). It killed me last night to watch TV on my laptop's monitor via USB TV Tuner.

Well I tried all the suggested fixes for the two IC's on the D board and was able to go from 7 blinks to 6 blinks. Thank you Bob for all your desoldering tips and the sockets, that part worked great. I do think this is a great site, I was so looking forward to plugging in the 2 new IC's and being another success story. After pricing out new TV's I have to try again at the repair. I was going to replace the IC on the A board but I realized that this is not the same as the 2 chips on the D board, wish I didn't order the 5 MCZ3001D now. Any help on the 6 blink fix would be greatly appreciated and would love to keep the kv40xbr800 out of the landfil.

Another successful D-board repair, and some tips!
First thanks to BobF and everyone that posted their experience with the D-board repair to this and other threads on this board. My KV-32xbr400 is now back in action with only a small monetary investment, plus some time. My repair consisted of replacing the IC6501 and IC8002 on the D board, as described several times here by others. A few tips from my experience:
1) If you can get the TV to turn on at all, even once, try to use the "Display, 5, vol -, power on" sequence to see the error code display, so you can be sure of the error codes.
2) My TV displayed both error code 4 and 7 once I got it on. Most of the time the set would try to turn on but fail. Sometimes my standby light blinked 4 times, sometimes it blinked 7 times. However it NEVER blinked in a repeating pattern, as some of the experts here say it must to be a "real" error code. I think that is a red herring, and that particularly for the error codes related to the D board problems, they may or may not repeat.
3) The HV wires pull right out of the flyback transformer if you pull hard enough. They seemed to go back in and lock in without any problem. But you have to pull hard. This allows you to remove the D-board easily and makes the desoldering and soldering jobs MUCH easier.
4) BobF's advice to cut out the old ICs pin by pin and then desolder the pins is very good advice. I don't have access to a good electronics store, so I could not purchase an appropriate cutter. Instead I took an old locking pen knife (not anything precious), centered the point on the very top of each leg of the IC to be removed, and (with the board resting on a firm surface), tapped the knife on the end with a small hammer. This cut through the tin leg without following through and damaging the circuit board underneath. I know this sounds risky, but if you try it you will realize that the impact required to cut the tin leg is much less than required to damage the board. This is MUCH easier and much less likely to damage the circuit board foils than trying to desolder the chips in those tight spaces.
5) Once the chips are cut out, I have always found that if you first flow a bit of fresh hobby grade rosin core solder on/into the existing soldered lead, it mixes with the original solder, and makes it much easier to melt with your iron. If you saw the old Ungar soldering iron I used for this you would laugh. I definitely followed BobF's method, and heated each lead and partially poked it though to the component side of the board from the other side using the iron. I then grabbed the leads one by one with a small pliars from the component side, and heated them from the other side until the pulled out with almost no force. Finally I sucked the solder out with my trusty old solder sucker. There is ONE pin on each IC that is much harder to desolder than the others, because it has a very large foil on the component side that dissipates the heat. Either be patient or get a hotter iron for that one.
6) Use a good socket as per everyones instructions. Use plenty of heat to flow the fresh solder through from the pin side to the component side.
7) One curious thing about my D-board which I have not seen mentioned here. It turns out that on my board, D8028 and R8199, which in series bring the +15V supply to VC1 of IC8002/MCZ3001D/HV driver chip, were sticking up from the board like they were a patch. There was plastic crud on them, probably to insulate them from accidental contact. The layout of the board in that area did not match the layout in the copy of the service manual I had. I only figured out what these components were by looking at the schematic and how they were connected.
 I got my copy of the DX-1A service manual (with full schematics) from "schematicsforfree.com". It is labelled as KV36XBR400.pdf, but it covers all the TV with the same frame version.
Thanks again to everyone. I still have a minor issue with this TV but I will post it separately.

Congratulations on your successful repair! (I just love to write that.)
And thanks for posting all the repair details.
Your comment on the single difficult pin on each IC was interesting. I remember that one pin was more difficult to remove than the others and I actually made note of that after the repair. But it never occurred to me that there was a different amount of foil on the component side that was dissapating the heat from the soldering iron.

Intermittent ABK error (error code 5) with KV-32XBR400
Hi all, here are the details about the relatively minor problem I am having with my TV now that I have replaced IC6501 and IC8002 on the D board.
The TV starts right up every time, and looks great. However after it has been running for a while, anywhere from 5 minutes to 5 hours, the picture "defocuses" and becomes dim, and then the CRT blanks out, while the sound stays on. Turning the TV off and then back on using the "display, 5, vol minus, power on" sequence shows self diagnostic code 5 is set. This is highly repeatable, in that I can reset the code counts to zero, and the next time it flakes out, code 5 is set.
Code 5 is labelled "AKB", and has to do with the cathode current being in range and in control so the colors are balanced. The first suggestion is to increase G2 (using RV9002 on C board), and then there are some others to follow up with.
I haven't tried this yet, and the reason is that I think that if the cathode current was low due to an aging electron gun etc, that this would be a startup problem and not a intermittent problem the comes up after the set has been on for some period of time. But that is just my gut feeling, and though I am fairly experienced with electronics, I am not an experienced TV technician.
I am guessing that the "defocussing" may be giving me a clue as to what the real problem is that might be, for example, possibly causing G2 or the focus voltage to fail after some time, and that failure is causing the cathode current imbalance self diagnostic to be triggered and the screen to be blanked.
The big question, and this is where I need the help of someone with more TV experience, is what is the most likely place to look for the "source" problem. I don't think it is in the D board circuits that I already fixed, because I expect that I would still be getting error codes 4 and 7 if they were the problem. But I think is certainly possible that something I did in the process of performing that repair might be causing this new problem.
Thanks for your help on this!
If there is a better thread to post this on please let me know, and I will move this message over there.

John,
I would probably start a new thread with a descriptive title. Maybe something like "Fixed KV-36XBR400 with IC replacements but TV only works for a limited time"
Hopefully that would get more replies than you might get on this thread.
In any case, here are a couple of suggestions.
Do you have any spare MCZ3001D ICs? If so, you might want to swap one of those with the current installed ICs. That would be very easy with the sockets you installed. It's probably a longshot but it's worth a try.
And since the problem develops over time, perhaps there's a problem with one of the newly soldered connections? Maybe a connection is affected over time as the TV heats up? So maybe it wouldn't hurt to touch up all of the new connections.
Good Luck!
Bob

Hi, guys . I have read many posts from the topic and decided to asksomeone for help. So, I have Sony KV - 30HS510 with DA-4 chassis, itworked great before but one day just stopped turning on every time whenI switched it on... this was strange... I plugged the cable off, waiteda minute and after that it started just normal. This problem started toappear more and more often. So I decided to do something, after aninspection I found the problem - +5 volt stabilizer. OK I fixed thatbut after a month the poor thing started with a new strange behavior.Now, when I turn on the television the picture starts from white-yellowwith white declined stripes and fast becomes white to super-white andafter a second turns off - I suppose this is a protection. So if anyonecan guide me .. or suggest something...
( I've attached photos to orient the others who are not so familiarwith the TV as I am). So, I've noticed when I disconnect the cablewith the three small cables which connects the CX board with D board(200V, GND, H1) the TV starts to work normally but without a picture,of course, the display is black. I suppose that it will guide most ofyou. Unfortunately, I don't have an oscilloscope, I have only anohmmeter. It will be pity to lose this nice and otherwise great workingTV with great sound.
Thank you all!

Sony KV-32HS510 TV
One morning, it decided it didn't want to turn on anymore.
Stayed in standby mode with 6 blinks over and over.
Blow dryer trick worked ONCE, left it on for 2 days, then 4 yo turned it off, couldn't get blow dryer trick to work again. Now blinking 6 times most of the time, but sometimes 7 after trying to turn it on every now and then.
Ordered the ics MCZ3001D: $6 a piece plus shipping, to replace the IC 6501 and IC 8002 (Radio Shack no longer carries the 18 pin ic sockets in store, but didn't want to wait for them to ship since I got my replacement ics already).
Bought (Radio Shack) small needle nose plyers: $6 (yeah I know, should have gone to Lowes or Walmart), Desolder braid/wick: $3.50, Smallest sized solder: $3.50, borrowed soldering iron from friend.
Laid TV on it's face on the tv stand with blankets to protect the screen (this thing is way too heavy to carry around, and I'm a big boy, lol), and worked on it vertically without having to unplug or unscrew anything attached to the D board. Again, simply left the D board alone where it was, attached with everything connected. One ic was accessible from both sides, one was covered by the little plastic casing bar of the frame. CAREFULLY cut off a 2 inch section of that plastic bar going across (it's just a cheap piece of hollow plastic, use some snips or something, just be careful not to touch that D board), and then had access to both ics from both sides.
Read and watched on youtube some tutorials on using desoldering braid and soldering tips.
Replaced both ics without having to cut the legs off them. Got most of the solder off with wick, verified with my flashlight on the other side of the board so I could see the light shining through the pin holes. With a little wiggle, ics came out no problem. Used desoldering braid one more time to get excess with the pins out of the way.
Replaced ic #1, plugged it in to test to see if I had to replace both, pushed the power button, and..........sigh, no. Discouragement sets in just a little, then I remind myself to keep expectations low as this is a last ditch effort, and moved on to ic #2.
Replaced ic #2, plugged tv in, pushed the power button and..............
You know, BobF and others, beyond having a tv back that would have been a while to replace (at least with something similar in value, this is a nice tv), beyond the money I saved (and didn't have) and beyond throwing away out of ignorance a tv that just needed a few ics, the feeling I got after now successfully fixing a broken xbox360 with the red rings of death, and now my 32 inch flat screen hd tv within a one month period of time, is unexplainable. My wife is officially bragging about her man all over her message boards, and my 4 kids haven't stopped calling me the greatest Dad ever. Sure it's just a tv and an xbox (and a bike, and a computer, and a basketball goal, and a DARNIT, will things just please stop breaking, lol), but for those of us in this economy who don't have the means to just replace it, there are options to doing without. Give it a shot, I was going to throw away anyways, might as well give it a try.
BobF and others, I thank you for your part in touching our lives with your knowledge and kindness.

Difficulty with removing the red wires to the Flyback is a very common problem and I ran into it myself on my KV-36XBR400.

Thank you Bob, for the quick response. I checked that thread and hope I can pull it out, with force:-)
I changed the two ICs, and the red light flashes 5 times, I switched the ICs again, the same problem. I will send the board to either Sony or Tristatemodule for a fix. Do you think I might have burned something else? Thanks!

You're welcome.
Before you send the board out for repair, here are some thing to consider trying:
- Retouch all of your new solder connections.
- If you disconnected anything during the repair, disconnect and reconnect those items.
- Make sure that the IC are firmly seated in the sockets.
- Use a ohm meter to check the continuity of the PCB trace material surrounding your new soldered joints. If you find a problem you can solder in a jumper.
One caution about sending the D-Board out for repair is that the power on problem might not be due to the D-Board. That was one reason that I didn't send my board to Tri-State. The Tri-State representative at that time suggested that I also send in the A and C boards so that they could be sure that they could find the problem.
And be sure to weigh the cost of any repair against the cost of buying a used, but working, model of the same or similar TV.
I think it's great to repair these sets and to save them from landfills. But you might find that it's less expensive to just replace the TV. I recently purchased a KV-36XBR800 with the matching Sony stand for $180 via a local Craigslist.org ad.
In any case, best of luck!
Bob

Thanks again, Bob. I will double check everythingtonight before I send it out to Sony.
For $65 hope Sony will fix it; Otherwise I pay only the shipping.
There was only a minor blue color problems on the left two corners before I changed the ICs; Lessons learned, a little later I believe I might only messed up the IC connections, and hope did not make any damages to other boards like you said. Thanks!

Ok so I have a KV-34HS510 that won't turn on, standby light blinks 6 times. This problem actually started this past April...went from unplugging the TV for a couple minutes to get it to turn on to hours then days then nothing. We bought it in March of '04 to replace our main TV and did'nt have HD channels until August of '08! But I have to agree with some of the other posts I've read the picture on these CRT's is(was)incredible! Anyhow I read the posts by BobF, sholliday and some others and decided to try the repair myself, replacing the two MCZ3001D chips on the D-board. I used the 18 pin sockets from Radio Shack and their desoldering wick, solder and soldering irons(15 and 25 watt, I'll explain later). Thanks sholliday for posting all the part numbers and prices, it was nice going into the store and being able to get exactly what I needed in one trip. When I attempted the repair I disconnected and labelled all the wires necessary to remove the D-board except the ones to the FBT. Most of the stuff I read had me thinking it best to leave those connected so I wouldn't damage anything. I did unhook the cap at the top of the CRT, however and after removing about eight screws I was able to flip the D-board and work on it resting on a folded towel(to protect it) behind the TV after pulling it away from the wall. I also removed the speaker "box" on that side and slid the chassis out after releasing the two clips. I was unsuccessful desoldering with 15 watts and the wick. Then I read some desoldering tips that suggested adding new solder to the old and that, along with stepping up to 25 watts did the trick, still using the wick. So I installed the new sockets and MCZ3001DB chips; still no picture and 6 blinks. Then I swapped them and had nothing; no blinks or anything, then swapped them back and had 6 blinks again. So I ordered two more chips from a different source that stated their chips are "Original Manufacturers" parts and that some places sell imitation parts!?!? Put those in and then I was getting 4,5,6 or 7 blinks but it seems to have gone back to 6 or 7 blinks after a number of attempts to get it to turn on. This last set of chips are marked MCZ3001D(no "B"). So now I'm checking for resistance from each of the pins to where they connect on the circuit board using a multimeter set on the 2M setting(it also has 200K, 20K, 2K and 200). I'm no electronics tech but my question is is this an acceptable way of checking my soldering? I'm just checking from each pin(on the bottom of the board) to where it appears to connect on the board. So far I get a no resistance .000 reading on all the IC8501 pins but an "open"(infinite res.)reading on pin 2 and am showing some resistance(don't recall the exact number)on pin 18 of the IC8002 pins. Maybe there's a schematic available or specs. to tell me what, if any, resistance I should have? I tried resoldering but nothing changed. Before I proceed any further I'd like to make sure I have the sockets soldered in properly. Any help or suggestions would be greatly appreciated. Maybe a proven source of replacement chips or are they really all the same? Local repair shops want $50.00 to diagnose but I'm guessing they're gonna tell me it needs the D-board especially now that I messed with it, so I'm not giving up yet. Almost $2000.00 for a TV and stand and we barely got five years out of it! Help!

Folks - just wanted to THANK all that have posted on the "no video / 7 blinks" problem. I thought it was over for my Sony KV-40VBR800 (aprox 6 years old) when I lost video. A search on the net led me to this site, and after about an hour of research was (relatively) convinced I had the D Board problem descrobed here. So I rolled the dice and found a replacement D board on Sony site http://servicesales.sel.sony.com/ecom/accessories/web/productSearch.do for 195.00 (Sony part # A1300319A). Argued with order processor and tech support - got nowhere except a $10 savings on expediated ship. Assy looks to be refurbished - 90 day warranty -learned only when I received shipment that they want the defective D board. Began the install last evening and it looked simple enough until I encountered the 2 HV wires on the Flyback challenge. THe red and white wires seemed to be permanently connected to the FB. The relacement assy shipped had NO HV wires installed. Back to this site for more research - consensis appeared to be to "pull wires until they disconnect". As I attempted this I was a bit freaked - it didn't feel right and feared I was destroying the FB. Sure enough, with enough force (I recommend using long nose pliers and leveriging against the top of the FB - don't pull with fingers), they both disco'd clean from the FB. Both disco'd wires had a clean, exposed wire - ready to be plugged into the FB on the new board. You will notice once pushed into the new FB, they are immediately as tight as they were an the old FB. Very unique setup. So for folks that are pulling on those wires and freaking that they are killing the FB - have faith - as others here have posted they do disco clean and can be reused. Then, disco the third (thick red) wire from the top of the CRT. If Sony doesn't chase me for the defective D board (anyone have experience with this ??) plan is to swap the MCZ3001D IC's (as described earlier in this thread) and retain as a spare. Last recommendation is - if you have the time and skill, try to replace the IC's prior to swapping the board. Could have saved about $180 bucks - by hey, I fixed the TV for about $210 !!!!!! And as was posted prior - when the set comes up after the swap it is indeed a real good feeling !!!!! Without the guidance provided by the good folks of this forum that would not have happened - and I want to thank you all !!!!!!!!

It's not unusual for power on problems to come and go. My KV-36XBR400 exhibited this behavior for several weeks before it failed completely.
So it may very well be that your set will, at some point, refuse to power on at all.
Regarding the purchase of parts, be aware that replacing any parts without any board level diagnostics is a bit of a gamble.
What model TV do you own?
Have you been having power up problems for a while?

If your TV's problems are due to problems with one or more of the two-D-Board mounted MCZ3001D ICs, you'll need:
Two MCZ3001 or MCZ3001DB ICs. (You can find these online for about $6 each. You might want to buy a couple of extra as spares.)
Two 18-pin sockets (These are optional. I used sockets for my repair.)
Soldering Iron
Solder
Desoldering Tool or Desoldering wick
For additional details on what I used, see the soldering tips I posted on Page 7 of this thread:
http://www.agoraquest.com/viewtopic.php?topic=1121&forum=34&start=90&select_page_number=7
Spend some time reading this thread as there are many excellent tips and lessons learned.
See also the following thread over on AVSforum's Television Troubleshooting thread:

You should be able to order the 18 pin sockets from Radio Shack, but why not check out other electronics stores in your area or order them on-line?

You can buy a PC board from Radio Shack for soldering practice but it won't have any components soldered to it. For many, desoldering is much more difficult than soldering.
Can you get a junked PC motherboard to work on? I practiced on a defective motherboard that I had never thrown out.
Maybe you can find something cheap on your local Craigslist.
For some soldering basics, check out the following link:

Hello all! New member and first time poster here so please bear with me. Just wanted to take a few minutes to express my thanks to BobF, JEHill and SHolliday, and to the many other members who posted helpful information that ultimately helped lead to the repair of my KV 34XBR800. Like some of you, I consider myself a "Jack of All Trades, and Master of None." That said, even with novice experience and a little common sense, I found the removal and replacement of the defective chip(s) to be easier than I thought, especially due to all the information I found on this forum. In an effort to ad to these through my experience, 'would simply like to offer the following observations:
- I was able to only partially remove my D-board and thus completed the repair with the set still on its platform in my living room. This was due to not wanting to tamper with 3 of the larger wires that did not want to disconnect. Also, I did not see any mention of the 4 clip-style connectors that connected from the D-board to the adjoining circuit board on the right side of the set (the TV's right). These must be disconnected carefully by pulling up and back.
- I used the "cutting" method to remove the old chips. I found it helpful to grind down the tips of my shears to a fine point so as to allow better access to the individual pins/legs. Access to these was also made easier by carefully bending back any resistors and diodes in the adjoining area.
- After the sockets were soldered into place, I used a multimeter to check my work by testing for continuity from front to back. This mostly helped to ensure a clean solder joint at each pin without shorts to the adjoining pins.
Lastly, I encourage anyone with symptoms of the dreaded IC problem to read through all the posts and make a go of it using all the information and recommended tools at your disposal. There's a nothing better than the feeling of effecting this type of repair with success.
Thanks again guys!
Manny

sounds as if Sony has a big problem here and mostly ignores it. The sets are overpriced and almost to a point unrepairable for what they want to charge. I think their should be a group of people go after them and sue for sure.

I'm sure that I am posting this correctly but...here it goes.
I found this forum two weeks ago while I was searching a problem with my kv34hs420. The symptoms were the same as you have discussed with the xbr's. I followed the instructions and went to ebay for chips. Followed the instructions on how to disassemble the flyback. Bought all the right tools. took note of all the soldering procedures. AND now I have my tv back!!!
I had to join to thank everyone that contributed to this forum and especially this thread that enabled me to repair my set.
Also I wanted to leave a post so that others with my model number may more easily find the solution. God knows Sony isn't helping.
Thanks, again to all!!

Having read ALL of the posts in this thread, purchasing the schematic available on-line, doing intensive Google-ing... I recently brought back to life a 6 year old 40XBR800. The set performs like new without any additional tuning!
Using components from coreweave (on eBay), I replaced two each MCZ3001D, 1200uF 250V electrolytic capacitors and 0.1 Ohm 1/2W fusible resistors on the "D" (power supply) board. The set has been now running perfectly for 30 days after being unusable for two months.
My personal thanks to each and every one of the posters in this thread for their unique pieces of information because, after all, it's not so much about watching legacy CRT HDTV... as it is what to do with a 340 LB shell!

Congratulations on your successful repair!
Did you replace the capacitors and the fusible resistors because the IC replacements didn't work? Or did you just want to replace everything at once? (Usually the IC replacements are all that's needed.)

Here are some soldering tips based on my experience replacing two D-Board ICs in my KV-36XBR400.
First a caution:
- Unplug the TV and leave it unplugged for a couple of hours before working on it. Be aware that you can still get shocked after the TV is unplugged because of stored electrical energy. Be careful what you touch. I was never shocked during my repair but I was pretty careful.
And here again is the excellent "how-to" circuit board link that I provided above:
http://www.pinrepair.com/begin/
It's so good it's worth linking twice.
Replacing ICs can be tedious and time consuming. I had some beginner level soldering skills before attemping the repair so I didn't have too much trouble soldering in the new components. What I did find difficult was desoldering the existing ICs to remove them. Desoldering can be a pain.
Before starting, clean the top and bottom of the circuit board with an aerosol spray electronics cleaner. Solder flows much better on clean surfaces. The circuit board on my TV was incredibly dirty from years of use.
Since an IC has a particular orientation on the board, it's a good idea to make a note of this before removing them. You can ruin the IC if you install it backwards. ICs usually have a dot or a notch to identify Pin 1. I also put a dot of "White-Out" on one end of the IC and on the adjacent circuit board. You can also find the "Pin 1" location labeled on the circuit board.
For desoldering I tried two different suction type tools and I found them both to be ineffective. I tried a squeeze bulb and a spring loaded tube. I just couldn't get either of those to work effectively.
What I did have luck with was desoldering braid/wick. That worked great although using it can be time consuming. You can buy desoldering wick online or at electronics stores such as Radio Shack and Fry's Electronics.
Before desoldering, you might want to remove the body of the IC by clipping each of the legs off. This is a suggestion that a local Sony service technician and it's the technique that I used. This allows you to desolder one leg at a time and you don't have to heat multiple legs at the same time to pull the IC. You can also clip all the legs on one side to allow you to bend the body of the IC up to allow easier access to the opposite row.
Leave as much of the legs in place as possible. A taller leg will be easier to grab when you want to pull it out. Use a very small shear cutter tool that you can find in an electroincs store. I bought an $5 Xcelite 170M at my local Fry's Electronics and that worked fine. Here's what one of these shear tools looks like:
http://www.remelectronics.com/ShowcaseDetail.asp?nShowcaseID=15
This tool needs to be small so that you can reach the legs without being blocked by the surrounding components on the board. I actually slid the rubber handles off the tool to allow for even easier access in some of the tighter spots.
After cutting the legs off, I removed as much solder as possible from the bottom of the circuit board. (The IC locations are labeled on both sides of the circuit board.)
After desoldering, I grabbed each leg on the top side with a hemostat and heated the leg from the bottom with the soldering iron. If you have a temperature controlled soldering station, I read in an electronics repair book that a temperature of 665 to 680 degrees F works well for desoldering. That's the temperature range that I used.
Be careful not to pull up any of the surrounding circuit board trace material.
After all of the legs were pulled I used soldering wick to remove any remaining solder in the pin holes. A bright light applied behind the circuit board can help you identify the pin holes where more solder needs to be removed. A darkened room can help here.
I used a head-mounted magnifying visor and that really helped with the fine soldering.
If you remove the board from the TV, take some time and label all of the connectors. That will save you a lot of trouble when you reinstall the board. I used masking tape folded back over itself for this. You may also want to take some digital photos.
Here's a photo that I took of the 18 pin MCZ3001D IC8002 on the D-Board of my KV-36XBR400 before I replaced it. As you can see, accessing the IC is not entirely easy with other nearby components:
As I noted previously, replacing IC8002 did not fix my TV. Replacing the other D-Board MCZ3001D IC, IC6501, did fix the TV. I didn't take photos of that IC but it is even more difficult to access. It's surrounded by a U-shaped aluminum heak sink which made removing the IC more difficult.
Before soldering in the replacement IC, seriously consider installing an 18 pin socket. This has several benefits. First, it eliminates any risk of overheating the IC when soldering it into place. Second, it makes a future replacement of the same IC a snap. Just pop the old one out and plug in a new one. Finally, a socket allows you to test fit the IC before installing the socket. This will allow you to bend the IC legs, if needed, to fit the pin holes without having to deal with the cramped confines of the D-Board. I had to slightly bend outwards the legs of both ICs that I installed. These sockets are less than $1.00 each and you can find them at Radio Shack and other electronics stores.
For the solder itself I bought a roll of very thin, 0.032" diameter, 60/40 rosin-core solder. The thin diameter works well for the fine work required. I also bought a bottle of liquid rosin soldering flux meant for electronics. I found this at Sears (Sears Product Number 9-80063). I applied the flux to clean the pin holes and to help the solder flow.

AMAZING!
Bob, you sir are the best. So simple, and I spent less than $35 USD! Got the chips from a guy in Delaware for $15 USD, with sockets! Solder gun(the 25 Watt, ~640 degree), solder(.032 rosin core), and desolder braid from Radio Shack. Saw other chips cheaper from China, etc, but I was in a hurry to get it fixed!
Only thing I had trouble with was the desoldering with the braid. I noticed after failing at the first chip and having to desolder each pin 2-3 times. If you hold the braid with your other hand, about 2 inches away from the pin, and slightly wiggle it back and forth you can see a small hole appear in the braid, then you can see the solder fill that hole! Also, just about the time you can feel the heat on your fingers 2 inches away is about the right time to pull away. All in all it took me just less than an hour to repair my TV(I already had the back off.) Got the second chip off in less than 5 minutes! Hit each hole one time each. I have beginner solder experience, soldering DB9 pin comm cables at work, and easy/large 2 pin components on motherboards. The chips were too wide for the sockets at first, but with a pair of needle nose pliers they all bend together and fit nicely. Just the opposite for the sockets going into the board, I had to bend the socket pins out just a little bit with the same needle nose pliers. After I put the sockets/chips in the holes with the needle nose, I had to bend a few of the pins over to hold it in place while I soldered other pins in, then straighten the bent ones back out and soldered them.
Oh there was also a slight issue with the 4 connectors that are between the D and A boards. I had to use my precision flat head screw driver to help pop the small clips on either side that it snaps into.
Tools I used:
25 Watt solder gun
.032 rosin core solder
desolder braid
phillips head #2(for removing the back case)
smaller precision screwdriver(for removing the board)
Great repair thread!
